一、前言红铅粉,也叫红丹或铅丹.二、三十年前,就有人把它当作热处理中的防渗剂.但由于这种防渗剂在烘干、热处理过程中容易产生裂纹与剥落,因此大表面的防渗很少采用,而仅用于某些工件的孔洞防渗.这样,人们对红铅粉的印象逐步淡薄了,以至在生产中忽视了它的影响.将带有红铅粉的零件,与其它零件一起装进渗碳炉,造成了大量零件返修与部分零件报废.为了解决这个问题,及引起同行们对红铅粉阻渗作用的重视,特写此文,供大家参考.
First, the preface Red lead powder, also known as red lead or red lead. Two or three decades ago, some people think of it as a heat treatment in the impermeable agent.But this impermeable agent in the drying, heat treatment process is easy Resulting in cracks and spalling, so large surface seepage control rarely used, but only for some parts of the hole impermeable, so that people gradually diminished the impression of red lead powder, and even ignored in the production of its impact. With the red lead powder parts, together with other parts into the carburizing furnace, resulting in a large number of parts repair and part of the scrapped.To solve this problem, and lead colleagues to infiltrate the role of red lead powder, this Man, for your reference.
