Technological method of increase of operational characteristics of details of engines and power installations by laser processing


The structurally functional circuit of formation of operational characteristics of details is submitted at laser processing by continuous radiation. Target parameters of such technological processes are depth of processing, the form of a zone of processing, property of the processed material, and also a roughness of a surface. Distinctive features of the offered approach from traditional are that the form of a laser stain and distribution of density of capacity of radiation are considered as key parameters of a mode of processing, the choice of parameters of a laser source and development of technological optical systems is carried out according to results of the decision of a return problem of heat conductivity. The developed technological method was applied at designing technology of increase of wear resistance of a cranked shaft of the piston engine.
