Figuration Control of Deposit in Friction Surfacing

Abstract:

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.
