Abstract
Изобретение относитс к сплавам на основе олова, используемым в качестве антифрикционных покрытий в подшипниках скольжени дл т желонагруженных машин. Целью изобретени вл етс повышение прочности, износостойкости и снижение коэффициента трени , что достигаетс дополнительным содержанием цинка. Сплав на основе олова содержит, мас.%: медь 7-8, сурьма 10-12, цинк 15-20, олово остальное. Из сплава методом электродуговой металлизации на стальные образцы были нанесены покрыти , показавшие следующие свойства: коэффициент трени 0,056-0,061, предел прочности 75,5-76,7 МПа, износ со смазкой при удельном давлении 10 МПа составл ет 21-24 мкм за 4 ч наработки. 2 табл.The invention relates to tin-based alloys used as anti-friction coatings in slide bearings for yellow loaded machines. The aim of the invention is to increase the strength, wear resistance and reduce the coefficient of friction, which is achieved by an additional zinc content. The tin-based alloy contains, in wt.%: Copper 7-8, antimony 10-12, zinc 15-20, tin else. From the alloy by the method of arc metallization, steel samples were coated, showing the following properties: friction coefficient 0.056-0.061, tensile strength 75.5-76.7 MPa, wear with lubricant at a specific pressure of 10 MPa is 21-24 microns in 4 hours groundwork 2 tab.
