Beschreibung
Zusammenfassung:	FIELD: agriculture; machine building.SUBSTANCE: invention relates to agricultural machine building and may and can be used for increasing of products operational resistance. Method of producing a wear-resistant boride coating on a steel part involves depositing an activator in the form of a flux P-0.66 and a charge with a boron-containing component and performing heat treatment. Part is placed on a heat-resistant ceramic gasket, the upper side of the part is heat treated at temperature of 1,200 °C for 5 minutes.EFFECT: provides for reduced time for obtaining wear-resistant coating of parts, increased thickness of coating and reduced cost of thermal diffusion borating.1 cl, 1 dwg Изобретение относится к сельскохозяйственному машиностроению и может и может быть использовано для повышения эксплуатационной стойкости изделий. Способ получения износостойкого боридного покрытия на стальной детали включает нанесение на деталь активатора в виде флюса П-0,66 и шихты с борсодержащим компонентом и проведение термообработки. Деталь помещают на термостойкую керамическую прокладку, проводят термообработку верхней стороны детали при температуре 1200°С в течение 5 минут. Обеспечивается сокращение времени на получение износостойкого покрытия деталей, увеличение толщины покрытия и снижение стоимости термодиффузионного борирования. 1 ил.
