Book Synopsis Laser Surface Modification of AZ31B Mg Alloy Bio-Implant Material by : Tso-chang Wu
Download or read book Laser Surface Modification of AZ31B Mg Alloy Bio-Implant Material written by Tso-chang Wu and published by . This book was released on 2018 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnesium and its alloys are considered as the potential biomaterials due to their biocompatibility and biodegradable characteristics but suffer from poor corrosion performance. Various surface modification techniques are employed to improve their corrosion resistance. In present case, laser surface melting was carried out on AZ31B Mg alloy with various laser energy densities using a continuous wave ytterbium laser. Effect of laser treatment on phase and microstructure evolution was evaluated by X ray diffraction and scanning electron microscopy. Multi-physics thermal model predicted time temperature evolution along the depth of the laser treatment zone. Additionally, electrochemical method and bio-immersion test were employed to evaluate the corrosion behavior in simulated body fluid medium. Microstructure revealed grain refinement and even distribution of Mg17Al12 phase along the grain boundary for laser treated samples leading to substantial enhancement in the corrosion resistance of the laser treated samples compared to the untreated alloy. The laser processed samples also possessed a superior wettability in SBF solution than the untreated sample. This was further reflected in enhanced bio-integration behavior of laser processed samples. By changing the parameters of laser processing such as power, scanning speed, and fill spacing, a controllable corrosion resistance and bioactivity/biocompatibility of the implant material was achieved.
Book Synopsis Laser surface treatment of a polymeric biomaterial: by : David Garreth Waugh
Download or read book Laser surface treatment of a polymeric biomaterial: written by David Garreth Waugh and published by Archives contemporaines. This book was released on 2014-02-01 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotechnology has the potential to improve people’s quality of life and holds the key to many unmet clinical needs. In the UK alone the biotechnology market is worth £4.5 billion and estimates of future growth range from 10 to 15%. This growth can only be driven by the increased use of inexpensive and easy to manufacture polymeric biomaterials. Although polymer science is a rapidly developing area of research, it remains that one of the most intractable problems encountered in biotechnology is that the performance of polymeric biomaterials depend upon both the bulk and surface properties. In this book the authors describe their work using lasers to modify the wettability characteristics of nylon 6,6 (as wetting is often the primary factor dictating the adhesion and bonding potential of materials) as a route to enhancing the surface in terms of in vitro osteoblast cell response. What is more, modifying wettability characteristics in this way is shown to be a highly attractive means of estimating the biofunctionality of a polymer. The book demonstrates and explains how the generation of a biomimetic surface on polymers using laser beams provides an in vitro platform on which to deposit and grow cells for either the development of implants or to reconstitute functional tissue. The correlative trends and generic characteristics which are identified in the book between the laser surface treatment, wettability characteristics and osteoblast cell response of the nylon 6,6 provide a means to estimate the osteoblast cell response in vivo. The book shows clearly that laser surface modification of polymeric materials has tremendous potential for application within the field of regenerative medicine.

Book Synopsis Processing, Surface Integrity, and Performance of Biodegradable Magnesium-calcium Implants by Laser Shock Peening by : Michael Patrick Sealy
Download or read book Processing, Surface Integrity, and Performance of Biodegradable Magnesium-calcium Implants by Laser Shock Peening written by Michael Patrick Sealy and published by . This book was released on 2014 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year, several million people suffer bone fractures caused by accidents or age related diseases in the U.S. alone. The annual incidence of bone fractures is expected to escalate in the coming years due increased life expectancy. The aggregate cost of treating bone fractures is estimated at a staggering $220 billion per year with an annual growth rate of 12%. Many of those fractures have to be surgically fixed by orthopedic implants to replace and act as missing biological structures. However, some patients require a secondary surgery to revise or often remove an implant which has failed. This imposes a heavy burden on the national healthcare system. Implants fail because they are designed to be permanent fixtures attached to bone; however, current implant materials made from titanium, stainless steel, or cobalt-chromium alloys cause stress shielding when left permanently in place. Stress shielding arises when metal implants carry the majority of stress because of their much higher Young's modulus than that of bone. As a consequence, bones are in a reduced stress state which allows them to become brittle and weak over time. Weakened bones are more susceptible to re-fracture and could potentially dislodge an implant causing severe harm and discomfort to a patient. There is a need for a biomaterial that is not permanent because it has the capability to degrade. This reduces stress shielding over time as well as the need for a second removal surgery. The similar mechanical properties of magnesium (Mg) to bone indicate it is an ideal implant material to minimize the damaging effects of stress shielding. Mg alloy implants have the ability to gradually dissolve and absorb into the human body after implantation. Mg alloys as a biodegradable implant material have the potential to minimize stress shielding as well as eliminate the need for secondary surgery while providing both biocompatibility and adequate mechanical properties. The critical issue that hinders the application of a Mg alloy implant is its rapid corrosion in human body fluids. Since corrosion occurs too quickly, mechanical properties cannot be maintained long enough for bone to properly heal. Therefore, how to control the biodegradation rate of Mg-based implants to make them commercially viable for orthopaedic applications is a critical technical barrier to realizing its great socioeconomic benefits. Laser shock peening (LSP) is an innovative surface treatment to impart deep compressive residual stresses and a surface topography across a broad area on an implant. The high compressive residual stress has great potential to slow corrosion rates and improve wear and fatigue performance. Also, the peened surface topography has the potential to promote bone ingrowth and attachment. The goal of this work is to develop and evaluate LSP as an enabling manufacturing process to control the corrosion and fatigue performance of a degradable magnesium-calcium (MgCa) implant by imparting a unique surface integrity. Fabricating such a unique surface integrity for various types of orthopedic implants relies on the peening process parameters such as laser power and the peening overlap. Unique surface integrities were fabricated by changing the laser power from 3 W to 8 W as well as changing the dent overlap ratio from 25%, 50%, and 75%. The effects of LSP on surface integrity, corrosion, and fatigue were investigated. The surface integrity was characterized by topography, microstructure, microhardness, and residual stress. Corrosion rate was assessed by potentiodynamic polarization in Hank's solution. Fatigue life was measured by rotating bending fatigue test in air. LSP reduced the corrosion rate for every tested condition. Also, LSP increased the fatigue life for every tested condition. LSP at high peening overlap ratios reduced the tensile pile-up region which resulted in lower corrosion rates and the highest fatigue life. Low overlap ratios caused more surface area and more pile-up regions which translated to higher corrosion rates and reduced the fatigue life. Increasing the laser power increased the surface roughness and the size of the pile-up region which caused the corrosion rate to increase. Also, surface topography and corrosion rate models have been established based on finite element analysis (FEA) and linear regression analysis, respectively. Therefore, a manufacturing process was developed that controlled the performance of a degradable MgCa implant within the ranges needed for orthopedic applications. In addition, this research has begun modeling the relationship between surface modification and clinical performance in order to be able to develop the next generation of orthopedic implants that can be tailored to degrade to meet individual patient's needs.
