| 1 | Surface structuring of case hardened chain pins by cold-sprayed microparticles to modify friction and wear properties显示文摘This paper presents the results of the application of a cold spray technique for structuring metallic surfaces with microparticles.The resulting changes in surface properties were characterized to observe their influences on the tribological behavior of the structured surface.The spray technique was applied to a technical component,a 16MnCr5 steel chain pin,designed to be mounted in a linear reciprocating tribometer.TiO_2 microparticles were used to structure the surface with a homogeneous distribution of singly dispersed particles,rather than a homogeneous closed coating on the surface.Tribometer tests were performed to directly compare structured and unstructured chain pins,and a significantly reduced sliding friction coefficient was observed for the structured pin.The pins were characterized in detail by surface analysis prior to and after application of the tribological load to set the surface parameters and surface chemistry,even on the microscale.It was confirmed that the particle structuring induced changes in the surface properties,and the durability of the changes after tribological loading was evaluated. | S.

| 11 | Microstructuring of titanium surfaces with plasma-modified titanium particles by cold spraying显示文摘Although the deposition mechanisms of the cold spray process are well studied, few reports regarding the use of surface-modified particles exist. Herein, titanium particles 3-39 μm in size and with an angular shape were modified in a plasma-enhanced chemical vapor deposition process in Ar, Ar-C2H2, and N2 plasmas. After Ar-C2H2 and N2 treatments, the respective presence of TiC and TiN on the particle surface was confirmed via transmission electron microscopy and energy-dispersive X-ray, X-ray photoelectron, and Raman spectroscopies. The powders were deposited on titanium substrates by cold spray experiments, where unmodified particles up to 10(xm in size exhibited a successful surface bon ding. This finding was described by an existing analytical model, whose parameters were achieved by computational fluid dynamics simulations taking the particle shape factor into account:. A good deposition of plasma-modified particles up to 30 μm in size was experimentally observed, exhibiting an upper size limit larger than that predicted by the model. Higher surface roughness values were found for plasmamodified particles, as determined by 3D scanning electron microscopy. The water contact angle indicated that argon treatment influenced the wettability. Tribological tests showed a decrease of the initial friction coefficient from 0.53 to 0.47 by microstructuring. | P.
