本文通过测定HA177－2，BFe30－1－1在3．5％NaCl和3．5％NaCl＋NH3（NH4+）溶液中的腐蚀速率、腐蚀磨损率和电化学行为以及观测腐蚀磨损后铜合金的微观形貌，研究了腐蚀后样品的表层性能。实验结果表明，NH3（NH4+）的存在加速了铜合金的腐蚀、腐蚀磨损，使腐蚀电位E(corr)明显负移、腐蚀电流密度i(corr)增加；氨或铵离子对铜合金腐蚀磨损的加速作用与腐蚀磨损过程中的氨致脆性有关。
In this paper, the corrosion rate, corrosion rate and electrochemical behavior of HA177-2 and BFe30-1-1 in 3.5% NaCl and 3.5% NaCl + NH3 (NH4 +) solution were measured and the microstructure of copper alloy Appearance, studied the surface properties of the sample after corrosion. The results show that NH3 (NH4 +) accelerates the corrosion and corrosion of copper alloy, negatively shifts the corrosion potential E (corr), and increases the corrosion current density (corr). The effect of ammonia or ammonium ion on corrosion and wear of copper alloy Acceleration and corrosion wear process of ammonia-induced brittleness.
