microstructure evolution and tribological performance of

Tailoring a material's properties for low friction and little wear in a strategic fashion is a long-standing goal of materials tribology Plastic deformation plays a major role when metals are employed in a sliding contact therefore the effects of stacking fault energy and mode of dislocation glide need to be elucidated Here we investigated how a decrease in the stacking fault energy 2013-9-23tribological properties of Ti 1-xCx coatings (with x being in the range of 0-1) deposited by reactive magnetron sputtering from a Ti target in Ar/C 2H2 mixtures at ~200 C The mechanical and tribological properties were found to strongly depend on the chemical composition and the microstructure

Study on Microstructure and Tribological Performance

The supersonic laser deposition (SLD) of diamond/Cu composite powder is studied over a range of laser power The deposition efficiency coating microstructure cohesive/adhesive bonding phase composition micro-hardness and tribological property of the diamond/Cu composite coating are investigated The results indicate that as laser power is increased deposition efficiency initially

Since the microstructure of the material under the contact strongly influences tribological performance the ability to control this microstructure is thereby of key importance However there is a significant lack of knowledge about the elementary mechanisms of microstructure evolution under tribological load

2020-4-6coating microstructure and tribological performance have been investigated as a function of the bias voltage ranging from Ub= -65 to -350 V The XRD results revealed that C/Cr coatings are amorphous at low Ub but became more crystalline when the Ub increased to -350 V High-resolution XTEM analysis indicated coating

The evolution of the microstructure in the AISI 420 stainless steel was analyzed by TEM and the hardness was analyzed via the nano-scratch tests It was found that an increase in the cumulative proton irradiation fluence could lead to the formation of vacancies or interstitial atoms on the surface layer of the AISI 420 stainless steel

Microstructure evolution and tribological performance of Cu-WS 2 self-lubricating composites microstructure hardness as well as friction and wear behaviors were investigated The dry sliding wear of the composites against GCr15 steel ball was measured at the load of 10 N in atmosphere condition The tribological behavior of the

Rare‐earth monosilicates (RE 2 SiO 5 RE: rare‐earth elements) such as Yb 2 SiO 5 have been developed for potential application as environmental barrier coating (EBC) materials Yb 2 SiO 5 coating would experience microstructure evolution under high‐temperature environment and accordingly its thermomechanical properties would be altered In this study Yb 2 SiO 5 coating was fabricated

Lead-free Bi-contained copper-steel bimetal bearing materials were prepared by powder metallurgy method their friction and wear tests were conducted by using the HDM-20 tribometer under boundary lubrication conditions The anti-friction anti-adhesion and load
