Book Synopsis Modification of Surface Tribological Properties by Microscale Pulsed Laser Processing by : Shixuan Chen
Download or read book Modification of Surface Tribological Properties by Microscale Pulsed Laser Processing written by Shixuan Chen and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a microscale pulsed laser beam deposits localized energy on a metallic surface, the irradiated spot can melt and cool down rapidly. A scanned surface area experiences a cycle of rapid heating and cooling treatments, which in turn causes microstructural evolution. The microstructural evolution leads to changes in mechanical strength and tribological properties. Besides, microscale pulsed laser processing controls micro-scale surface features. Therefore, it is a promising technique to produce surfaces with improved tribological performance. The objective of this thesis is to investigate the microstructural changes and the multi-scale tribological performances of the microscale pulsed laser processed surfaces. The tribological performances are related to the microstructures to understand the underlying mechanisms of the enhancements. The thesis starts with applications of microscale pulsed laser processing on a couple of metallic alloys to study the microstructural changes in the processed area, such as phase transformation and chemical redistribution (Chapters 2 and 3). Initially, this method is applied on Ti6Al4V alloy to create continuous surface layers with altered phase components. Two laser powers are used to achieve low and high energy inputs. The obtained phases are predominantly martensitic Îł' and Îø phases due to the extremely rapid heating and cooling in the melt zone and heat affected zone. Higher laser power produces thicker martensitic Îł' surface layers several microns into the processed surface, exhibiting higher hardness compared to the surface processed by low power laser. The hard martensitic surface layer resulting from microscale pulsed laser processing facilitates superior resistance to abrasive wear and low cycle fatigue wear. Then, the influence of microscale pulsed laser processing on chemical distribution and wear resistance of A384 casting aluminum (Al) alloy is investigated. The large proeutectic silicon (Si) precipitates in the base material melt and disperse into the Al matrix during melting. Thanks to the rapid cooling, the dispersed Si lacks time to grow. Thus, the process results in a homogeneous remelted surface layer with well-distributed small Si particles. The hardness of the layer becomes more uniform compared to the base material, which is an expected consequence of elemental homogenization. Besides, the hardness and wear resistance of the homogeneous surface is higher than the unprocessed Al matrix. Microscale pulsed laser processing can also cause significant geometric and chemical changes in a multi-material system. Chapter 4 and 5 of this thesis study those changes on S7 tool steel surfaces dip-coated by nanoparticles and melted by microscale pulsed laser. The nanoparticles can either mix with the substrate or agglomerate on the surface, depending on the laser settings and nanoparticle properties. The magnitude of the fluid flow in the melt pool increases as the laser power increases. Higher laser powers result in stronger flow of the molten mix and help mixing of nanoparticles in the substrate. Besides, nanoparticles with good wettability, solubility and reactivity with the substrate can mix with the substrate and form alloyed regions; whereas nanoparticles with poor wettability agglomerate on the surface and form clusters. For instance, thanks to their good wettability and solubility in steel, SiC nanoparticles mix with the S7 tool steel during processing and form alloyed regions. The alloyed regions exhibit higher hardness and wear resistance compared to the substrate processed without nanoparticles. That enhancement should come from the strengthening effect of the nanoparticles dispersed in the metal matrix. In contrast, due to the poor wettability in liquid iron, Al2O3 nanoparticles form clusters on the S7 tool steel surface after microscale pulsed laser processing. The clusters exhibit higher hardness, denser structure and stronger bonding to the substrate compared to the as-coated layer. Therefore, the clusters can withstand severe scratching and exhibit excellent wear resistance. In this study, microscale pulsed laser processing is applied on metallic surfaces to achieve enhancement of the multi-scale tribological properties. The enhancement can be realized by altering the phase component, chemical distribution and introducing reinforcements. The method is flexible with the scale and the selection of the processed material, therefore has a great potential in micro device and small part manufacturing.

Book Synopsis Laser Generation and Applications of Micron and Submicron Scale Features on Metals by : Robert William Lloyd
Download or read book Laser Generation and Applications of Micron and Submicron Scale Features on Metals written by Robert William Lloyd and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the formation of and applications of self-assembled structures on metals. Primarily the focus of this PhD project is on the formation of surfaces structures on stainless steel (AISI 304) but other metals have been studied. Laser generated surface structures have been applied to the modification of wettability and reflectivity with a view towards developing these processes for industrial applications. Compared to conventional techniques for the modification of wettabililty, lasers offer the advantage of being a relatively simple technique for the modification of surface structure, reducing the need for complex processes. It is hoped that investigations into the reduction of surface reflectivity will have applications in the conversion of solar energy into useable power in the form of solar thermal energy. The production of self assembled structures is demonstrated using diode pumped solid state (DPSS) Nd:YVO4 lasers operating at wavelengths of 532 and 1064 nm. It is shown that the production of surface microstructures is highly dependant on the correct laser fluence and requires multiple pulses and processing passes. At 1064 nm wavelengths, it has been found highly reproducible surface structures can be formed by carefully controlling laser fluence and scanning speed while keeping the optical arrangement relatively simple. In addition to microstructure formation, the use of ultrafast femtosecond lasers, operating at 400 and 800 nm wavelengths has verified the production of laser induced periodic surface structures. Additionally, the stationary method used to produce these surfaces has been adapted to cover large surface areas with sub wavelength ripple structures with periods of ~295nm and 600nm. Applications of laser surface microstructures on metals have been studied in an effort to produce hydrophobic and superhydrophobic surfaces on metals. It has been found that the roughness change produced by laser processing induces composite wetting when water droplets are introduced to the surface. Contact angle measurements and small angle XRD analysis of laser processed stainless steel (AISI 304) have shown that surface wettability decreased over a period of approximately one month, leading to steady contact angles of over 140°. This is attributed to the formation of a magnetite (Fe3O4) oxide layer in the period after laser processing. The effect of surface microstructure on surface reflectivity has also been studied. It was found that laser induced surface microstructures on copper can decrease surface reflectivity by almost 90%. A comparative study of the effects of surface roughness and chemistry on the optical absorption of copper is given, finding that these surfaces are competitive with contemporary coatings.
