Изобретение относитс  к порошковой металлургии, в частности к способам нанесени  покрытий из порс лконых материалов , и может использоватьс  в машиностроительной прсЭлышленности ДЛ1. поверхностного упрочнени  деталей машин.The invention relates to powder metallurgy, in particular to methods for applying coatings to porous materials, and can be used in the engineering industry DL1. surface hardening of machine parts.

Известен способ нанесени  покрытий из порошков на внутренние поверхности цилиндрических деталей, заключакадийс  в том, что слой порошка засыпаетс  в зазор между деталью и с -ержнем, вращаетс  с деталью в зоне источника нагрева и припекаетс  к детали ij.A known method of coating powders on the inner surfaces of cylindrical parts concludes that a layer of powder is poured into the gap between the part and the rod, rotates with the part in the zone of the heating source and burns to part ij.

Недостатком способа  вл етс  низка  производительность и неравномерность получаемого сло .The disadvantage of this method is the low productivity and unevenness of the resulting layer.

Наиболее близким к предлагаемому изобретению по технической сущности и достигаемому результату  вл етс  способ нанесени  покрытий погружением обрабатьшаемых изделий из термопластов в псевдоожиженный слой порошка, нагретого- до температуры плавлени The closest to the proposed invention to the technical essence and the achieved result is a method of coating by immersing the processed products from thermoplastics in a fluidized bed of powder heated to the melting point

термопластов 2,3 .2.3 thermoplastics.

Недостатком этого способа  вл етс  непрочное сцепление частиц с заготовкой при нанесении покрытий на металлические поверхности, а также не равномерность получаемого сло .The disadvantage of this method is the fragile adhesion of the particles to the workpiece during the coating of metal surfaces, as well as the non-uniformity of the resulting layer.

Цель изобретени  - повьлиение точности сцеплени  частиц порошка с наружной поверхностью цилиндрической заготовки и получение равномерного 5 сло  покрыти .The purpose of the invention is to increase the accuracy of adhesion of powder particles to the outer surface of a cylindrical billet and to obtain a uniform 5 layer of coating.

Это достигаетс  тем, что заготовку подвергают обкатке по внутренней поверхности емкости с приложением давлени .This is achieved by subjecting the billet to running around the inner surface of the container with the application of pressure.

10 На чертеже изображено устройство дл  осуществлени  предлагаелюго способа .10 The drawing shows a device for carrying out the proposed method.

Способ ос тдествл етс  следующим образом,The method is as follows:

5 В емкость 1 с псевдоожиженнь) слоем порошка 2 помещаютцилиндрические заготовки 3, установленные в приспособление 4. Нагрев производ т .источником тепла 5, Приспособление 4 вращаетс  и заготовки под действием прикладываемого давлени  прижимаютс  к стенкам емкости и вращаютс  вокруг своей оси, Порошок, попадающий между стенкой емкости и заготовкой, напрёс5 совываетс  и припекаетс  к ее поверхности .5 A container 2 with a fluidized bed of powder 2 places the cylindrical billets 3 installed in the fixture 4. The heat is produced by a heat source 5, The fixture 4 rotates and the billets are pressed against the walls of the container and rotate around its axis, Powder falling between the wall of the container and the workpiece, the forearm 5 joins and burns to its surface.

Пример. Примером конкретного применени  способа  вл етс  процесс нанесени  дисульфида молибдена на поверхность поршневого пальца.Example. An example of a specific application of the method is the process of applying molybdenum disulfide on the surface of a piston pin.
