Tribological properties of CrN coating deposited on 20CrMo

A CrN coating was deposited on the piston pin material 20CrMo.The tribological properties of 20CrMo and CrN coating against tin bronze QSn7-0.2 were compared by pin-on-disk tests under dry friction and oil lubrication,respectively.The cross-sectional morphologies and structures of the coating were characterized through scanning electron microscopy and X-ray diffraction.The hardness Steel Grades - Stainless Steel Tube Stainless Steel Pipe1035 (HR) Intermediate carbon higher in strength and hardness than low carbon steel.Used for studs,bolts etc.1040,1045 (HR,CF) Used when greater strength and hardness is desired in the as rolled condition.Good for hammer forge processes.SCM420H - SteelJIS - Datasheet,Chemical composition SCM420H datasheet,SCM420H mechanical properties,SCM420H technical specifications.Chemical composition of Japanese steel SCM420H.Standards of SCM420H.Tensile Strength of SCM420H.Elongation of SCM420H.Density of SCM420H.Brinell,Rockwell,Vickers hardness of SCM420H
