摘　　要：研究了建筑用钎焊合金BCo46、DZ468和BNi-2在热腐蚀条件下的腐蚀行为。结果表明,在热腐蚀条件下,合金BCo46的抗腐蚀能力强于合金DZ468和BNi-2。3种合金在热腐蚀环境中都出现了硫化物析出和氧化薄膜溶解现象。The corrosion behavior of the brazing alloy BCo46, DZ468 and BNi-2 used in construction under the condition of hot corrosion was investigated. The results show that the corrosion resistance of the alloy BCo46 is better than that of the alloy DZ468 and BNi-2 under the hot corrosion. The precipitation of sulfide and the dissolution of oxide film appear for the three alloys in the hot corrosion environment.
