PECULIARITIES OF CREATION OF HEAT-RESISTANT FRICTIONAL MATERIALS,
Abstract
Principles of creation of frictional materials for work at high temperatures and pressures reduce to the following: use the friction series and series of wear-resistance to make the selection of friction ingredients; with this the thermal conductions and the influence of ingredients on counterbody of the friction pair should be taken into account. The binder should be heat-resistant, should preserve good elastic properties at high temperatures, and also should possess the ability to form coke-like products with good mechanical properties. The binder should have high adhesional properties. The content of organic binding should be minimum; this favors application of ingredients with little developed active surface. Increase and stabilization of coefficient of friction can be attained by: (a) introduction of oxidizers, promoting a lowering of the formation of liquid products of destruction and retaining the reduction of reactors; (b) additional heat treatment of friction material at a temperature of 400-600 degrees without an oxidizing medium. Every recommendation should be carried out in such a manner as to ensure the creation of frictional layer as a result of the use of heat emitted during braking. (Author)
