自保护硼铝共渗膏剂研究

试验以价格低廉的硼砂为供硼剂，采用膏剂自保护技术进行了硼铝共渗试验，试样渗后表而光洁，解决了硼砂引起的粘结问题。试学命结果表明：粘结剂的含量对膏剂表面状态有很大影响，调整还原剂和硼砂的比例或者降低硼砂含量可以避免硼砂粘结。为获得耐蚀耐磨性能，综合考虑致密性、相组成和渗层厚度的影响，在保证致密性及相组成的情况下，渗层只要具有一定的厚度就可以，其结果为研制一种新型能耗低、效率高的硼铝共渗工艺提供了基础。

Study on the Self-protective Boron-aluminizing Paste

Utilizing inexpensive borax as source of boron and using the technology of self-protective paste, the boron-aluminizing test were carried out. The surface was smooth, the problem of adhesion by borax was solved. The results showed that the content of adhesive agent has great influence to the surface status of paste.. Changing the ratio of lucigenin and borax or reducing the content of borax may avoid the adhesion of paste. In order to obtain corrosion and wear resistant parts, and comprehensively consider the effects of compactness ,phase composition and thickness of alloying layer, a certain diffusion thickness is available, if compactness and phase composition are suited. These results provided the foundation to develop a relatively new Boron aluminizing technology with lower consumed energy and higher efficiency.
