POSSIBILITIES OF INCREASING THE DURABILITY OF THE ARBOR TYPE COMPONENTS OF HEAT ENGINES

Abstract

The durability and friability of heat engines are dependent on the tribological behaviour of the components and on the specific greasing conditions. The part of tribology also includes aspects of the technical conditions of the engine, the technical, functional, technological and economic criteria of deciding the limits, as well as the procedures to determine the physical and moral wearing (attrition). The process of wearing (attrition) means an unwanted modification of the dimensions and qualities of the surfaces and their position and geometrical shape. Thermic metallisation is one of the technological procedures of processing metallic materials which allows obtaining some new surfaces which fit to specific requirements. The intervention upon a worn-out piece or component in order to regain or remake the initial technical state through the application of some extra material, thus ensuring the working period and the conservation of the structure of the basic material is called reconditioning. The term reconditioning always refers to a reference point while mending refers to an entire system taken on the whole.
