摘　　要：采用静态挂片和SEM方法,考察了亚磷酸三苯酯在环烷酸腐蚀体系中对A3钢的缓蚀性能。结果表明,亚磷酸三苯酯具有很好的缓蚀性能,它可以在金属表面形成致密的膜,该膜在不添加缓蚀剂的情况下,在环烷酸中可以保持60h以上的耐腐蚀性能,显示了亚磷酸三苯酯作为缓蚀剂具有很好的后效性。The inhibitory performance of triphenyl phospite in naphenic acid to the corrosion of A3 steel was investigated by the mass loss method. The results showed that triphenyl phospite yields an excellent inhibitory performance. Triphenyl phosphite could form a tight protective film on the surface of metals. The pre-adsorbed film could resist to the corrosion of more than 60 h in naphthenic acid without addition of any corrosion inhibitors. The film was of good persistency and adsorptivity.
