In the monograph methodological bases of selection of method of coating, design of technological processes of hardening and recovery of the wearing surfaces of parts using a systems engineering analysis and information support technologist. The mathematical model of plasma spraying of materials with different thermal conductivity and methods criteria for evaluation of technical and technological opportunities of a plasma coating method. Describes the methods and results of experimental studies, the analysis of the conditions and causes of loss of efficiency of processing equipment APK. The proposed scientific and methodical approach to the justification of expediency of the recovery and strengthening of the working bodies and parts expensive imported technological equipment. The proposed mathematical model describing the physical processes in plasma coating for various applications. The structure of the algorithm for solving the task of hardening and recovery of worn parts plasma methods on the basis of the integrated CAE system. This monograph is intended for employees of scientific research institutions, specialists of machine-building production and enterprises of technical service, as well as teachers, postgraduates and students of agricultural engineering areas of training.
