Analysis of Manufacturing Process of Shaft Parts Based on Thermal Spraying

摘要

Thermal spray technology is one of the key supporting technologies of remanufacturing engineering, and it is an important technical means to realize the rapid recovery of the surface dimensions of the damaged parts, to improve the performance and prolong the service life. In this paper, the main shaft of the waste machine tool is used as an example, the outer surface of the shaft is repaired by plasma spraying technology. The finite element software ANSYS for thermal spray coating system of temperature and residual stress of linear elastic analysis, get the same profile nodes in different depths of temperature versus time curve, profile and different radial stress distribution curve for thermal spray remanufacturing process optimization provides more accurate reference data.
