轴承零件淬火前常用浸涂硼酸然后加热淬火的方法,以减少零件氧化肥碳。本文介绍一种改进方法,即将工件加热300～400℃,代替酒精对硼酸的催化涂敷效果,使硼酸酐在工件表面均匀涂布。其特点是方法简单,质量效果较好,成本较低,适宜在中小轴承厂推广。 Bearing parts commonly used before immersion boric acid quenching and heating methods to reduce the part of the carbon oxide fertilizer. This article describes an improved method, that is, the workpiece is heated 300 ~ 400 ℃, instead of the alcohol on the boric acid catalytic coating effect, the boric anhydride evenly coated on the workpiece surface. Its characteristics are simple method, good quality and low cost, suitable for small and medium-sized bearings factory.
