Structural, mechanical, tribological, and corrosion properties of a-SiC:H coatings prepared by PECVD

Mechanical and Tribological Properties of Plasma Deposited a-C:H:Si:O Films

“…H 3 /E 2 increases from 1.6 to 7.9 MPa as oxygen is incorporated into the plasma. Even though the elasticity index agrees well with values reported in the literature for a-Si:C:H films deposited by PECVD (Guruvenket et al, 2010), the plastic deformation resistance found here is around 50 times lower. According to the Johnson analysis (Tsui et al, 1995), H 3 /E 2 , is proportional to the load at which the material starts deforming plastically under the action of a rigid sphere of radius r. Therefore, to obtain a material highly resistant to plastic deformation H should be high and E low, consistently with the H/E parameter.…”

Tribocorrosion test protocols for sliding contacts

“…8 Note that M c-w could be positive in cases where corrosion reactions act as lubricant and reduce wear. M c-w is relevant in the case of coated substrates, where liquid infiltration through pores and defects in coatings can lead to the reduction of tribological properties of substrate/coating systems [20][21][22].…”
