“…It can be used to make artificial prosthesis and other devices, and is considered as one of the attractive metal materials in biomedical applications. 16,17 A few scholars used other non-conventional techniques to explore the porous titanium. Electron beam melting (EBM) is a non-conventional method for manufacturing porous bio-implants, which has the advantages of short processing time and low cost.…”

Porous metal materials are widely used in heat-absorbing, biomedical parts and other fields because of their excellent mechanical properties and biocompatibility. Further applications of porous metal materials are inseparable from secondary precision machining. However, traditional cutting methods tend to compromise the original porosity of the material surface. Electrical discharge machining (EDM) is a type of non-conventional machining method which is more preferable to overcome these defects. In the present study, the main target is to investigate the effect of four input electrical machining parameters (current, frequency, efficiency and gap voltage) on the five output responses (material removal rate (MRR), electrode wear, surface roughness (SR), noise and time consumption value of environmental particulate matter (PM2.5)) when electrical discharge machining porous 316L stainless steel and compared with that of pure 316L stainless steel. The Taguchi method was employed to determine the relationship between electrical discharge machining parameters and output responses. The analysis of variance (ANOVA) was used to evaluate the effect of input parameters on output responses. The effects of electrical machining parameters on above responses were analyzed by main effects, and the order of influence was obtained, respectively. Finally, the surface morphology was observed by scanning electron microscope (SEM), and the effect of electrical machining parameters on the characteristics and formation of machined surface of porous stainless steel was mainly analyzed.

“…Surface deformation, cracks, and pits caused by corrosion may accelerate the wear and shorten the service life of the railway tracks [30]. Luo et al [31] found that both surface hardness and corrosion resistance of the 304 stainless steel coating were significantly improved due to the generation of compressive stress by LSP treatment. Lu et al [32] investigated the influence of LSP on the hot corrosion behaviour of Ti-6Al-4V alloy processed by the selective laser melting technology.…”

Laser Shock Peening (LSP) was introduced to reduce the residual stress and improve the wear and corrosion resistance of Fe-based 43X coating on worn U71Mn steel by laser cladding technology. The tensile stress decreased with increasing of laser power density and impact times, finally, transferred to compressive stress. The microstructure of the coatings was refined due to LSP treatment. The refined microstructure and existence of retained Austenite phase resulted in significant improvement in microhardness and anti-wear performances. The coatings after LSP process presented better corrosion resistance. However, impact three times with a higher power density has negative effect on improving the corrosion resistance.
