采用熔盐脉冲电解法在20钢表面制备出渗硼层,与其它渗硼方法所得渗层的组织形貌进行了对比,并对所得渗层的耐蚀性及其机理进行了研究。结果表明,熔盐脉冲电解渗硼法比其它方法温度低、耗时短,渗硼效率高,所得渗层较厚,组织致密,呈梳齿状嵌入基体,与基体结合牢固。渗硼层耐硫酸、盐酸和氯化钠腐蚀,不耐硝酸腐蚀。
- Abstract:
-
Boronized layer was prepared on 20 steel surface by molten salt pulse electrolysis,microstructure and morphology of the layer were compared with those got from other boronizing methods,and corrosion resistance and mechanism of the boronized layers were studied. Results showed that the molten salt pulse electrolysis boronizing was better than other methods with its low temperature,short time,high efficiency,thick layer,dense microstructure and the comb-tooth-like layer was embedded into the matrix with firmly bonding. The boronized layer could resist sulfuric acid,hydrochloric acid and sodium chloride,but it couldn’t resist nitric acid.
