COMPARISON STUDY ON ANTI-EROSION PERFORMANCE OF NECKEL PLATED COATING WITH THAT OF BRASS
摘要
利用自制的汽轮机凝汽器铜管模拟试验装置
进行Ni P、Ni W镀层与黄铜HSn70 1A模拟管端冲刷腐蚀试验。结果表明
黄铜管管端采用Ni P、Ni W镀层可防止冲刷腐蚀
显著提高黄铜管抗冲刷腐蚀能力和使用寿命。与HSn70 1A黄铜管段试样相比
Ni W镀层可提高抗冲刷腐蚀能力近5倍
Ni P镀层可提高抗冲刷腐蚀能力3倍多。
Abstract
Using selfmade simulation test stand for copper tubes in condenser of turbines
simulated test of tube erosion for NiP and NiW plated coating and brass HSn 701A has been carried out.Results show that the brass tube end with NiP or NiW plated coating can prevent erosion
enhancing obviously the ability of antierosion and service life of the brass tubes.Comparing with specimen of HSn 71A tue section
the NiW plated coating can enhance approximately the ability of antierosion to 5 times
the NiP plated coating can enhance the ability of antierosion to three times.
