一、前言固体渗硼工艺经历了几十年的研究和发展,七十年代初才开始逐步应用于工业生产,由于该工艺具有渗剂来源广、价格便宜、不受设备条件限制、操作容易、工艺质量稳定、表面易清理等优点,近几年发展十分迅速,相继出现了粉末、颗粒、球状、膏剂等工艺方法。 I. Introduction Solid boronizing process has undergone several decades of research and development, and began to be gradually applied to industrial production in the early 1970s. Due to its wide source of permeation agent, low cost and not restricted by the equipment, the process is easy to operate, Process quality and stability, easy to clean the surface, etc., in recent years the development of very rapid, have emerged powder, granules, spherical, ointment and other processes.
