После отжига материал имеет структуру скоагулированного или наход щегос в стадии коагулвдии цементита на фоне твердого раствора меди и молибдена в ot-железе, а также содержит включе-i ни сульфидов частично в цементной оканв таблице приведены физико-механические характеристики (Исследованных материа-GLANDS The material is prepared as follows: the amp & powder ingredients in certain ratios, corresponding to the claimed composition, are thoroughly mixed until a homogeneous mixture is obtained. Then, the obtained mixture is pressed into blanks at a specific pressure of 5-7 t / cm, after which 11OO-120O ° C is sintering for 1, O-3, O hour In a protectively reducing atmosphere of an endothermic hydrogen gas or dissociated ammonia to prevent oxidation and decarburization. The material can be annealed in a protective atmosphere of endothermic gas, hydrogen or dissociated ammonia LRA 65O-760 ° C. The following materials were investigated, weight. % :; W Molybdenum Disulfide4 56 Copper2.7 3.0 5.0 Iron Else Ostal-Osnoethal The following composition of material is considered optimal, wt. %: Molybdenum Disulfide 5 Copper3; Graphite (carbon) 1,3 (0,9) Iron Others The proposed material has the structure of sorbitol-like perlite doped with copper and molybdenum, with the inclusion of sulphides, creating a release film on rubbing surfaces during the operation of parts. After annealing, the material has a coagulated or coagulated cementite structure on the background of a solid solution of copper and molybdenum in ot iron, and also contains sulphides, including partially in the cement okan, the table shows the physicomechanical characteristics (
