Mechanical Study of High Resistance Silicon Carbide Based Multi‐Nano‐Layers Grown by Multifrequency PACVD

Type: article
Abstract: Titanium alloys are commonly used to lighten aeronautical structures. Unfortunately, their poor tribological properties need to confer onto the surface both high mechanical resistance under load and low friction/low wear against other metals. Based on amorphous silicon carbide (a‐SiC:H), periodic multi‐nano‐coatings have been found to be candidates for this use. Such coatings were deposited on Ti surfaces using multifrequency plasma CVD devices. Scratch‐testing measurements have revealed that the critical loads corresponding to cohesive/adhesive cracks are significantly increased using multilayered stacks. Fretting‐wear tests also revealed the influence of multilayer architecture and preliminary analysis of wear tracks and material transfers leaded to a first classification of the coatings.
