Titanium nitride (TIN) thin film possess excellent wear resistance, a golden color, and other desirable properties. They are t,herelore quite common in industrial parts and components. TIN films can be fabricated by many methods among which vacuum arc plasma deposition is gaining popularity beause of the ewe to
Friction Surfacing is an advanced surface modification method, so it is of great importance
to study figuration mechanism of deposit in friction surfacing process for controlling deposit’s
quality. By friction surfacing, consumable-rod of 1Cr18Ni9Ti (321)was surfaced on the substrate of
mild steel (1020) by different process parameters (rotation speed, force and traverse speed). The
effects of process parameters on deposit’s figuration are discussed. Experiments show that deposit’s
width and thickness decrease linearly with increasing consumable-rod rotation speed; deposit’s width
increases and its thickness decreases with increasing force. If traverse speed between substrate and
consumable-rod increases, deposit’s thickness and width decrease simultaneously. According to
conservation of mass, the material transferring & figuration rules in friction surfacing were analyzed,
which explains the experimental results as well. So, figuration control methods of deposit in friction
surfacing are set up. In practice, process parameters must be chosen properly to ensure good
figuration. Only if process parameters are inside the feasible area, material can transfer fluently and
deposit with good figuration could be got.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
