INVESTIGATION OF INORGANIC SALTS FOR THE PURPOSE OF USING THEM AS HIGH-TEMPERATURE LUBRICANTS
Abstract
In recent years there has been a sharp increase in the requirements with relation to thermal and thermo-acid stability of lubricating materials. One is confronted with the problem of maintaining high lubricating quality and at the same time creating lubricating materials which are capable of functioning at temperatures up to 600 or 800 C. In order to solve this problem much attention is being given to research in the field of solid lubricants and films obtained from graphite, molybdenum sulfide, metal oxides, etc. Processes have been developed for thermochemical treatment of friction surfaces, particularly sulfidation, where the ferrous alloys are treated with a mixture of salts in a bath with high temperatures. Judging by the data from the literature solid lubricants can work in the air at a temperature close to as high as 400 C. However, there is a requirement for new liquid lubricating materials which are stable at high temperatures. The principal advantage of aliquid lubricant lies in the fact that it assures removal of the heat from the friction surfaces and renewal of the lubricating material in the area of the friction.
