本文分析了垃圾焚烧炉循环流化床（CFB）锅炉水冷壁管防磨热喷涂涂层的失效机理：S及碱金属等引起的S腐蚀导致涂层鼓泡,在炉内高温物料的磨损下涂层逐渐破损、剥落直至加速剥落失效。热喷涂防腐抗磨双效复合涂层能很好的解决了垃圾焚烧炉水冷壁同时存在的高温腐蚀和磨损的问题。
本文分析瞭垃圾焚燒爐循環流化床（CFB）鍋爐水冷壁管防磨熱噴塗塗層的失效機理：S及堿金屬等引起的S腐蝕導緻塗層鼓泡,在爐內高溫物料的磨損下塗層逐漸破損、剝落直至加速剝落失效。熱噴塗防腐抗磨雙效複閤塗層能很好的解決瞭垃圾焚燒爐水冷壁同時存在的高溫腐蝕和磨損的問題。

This paper analyzes the failure mechanisms of anti-wear thermal spray coatings on water wall tube of the wastes incineration Circulating Fluidized Bed （CFB） boiler. Sulfur corrosion caused by alkali, S and the Compound above lead to coatings bubbling, which are then gradually abraded by the high temperature flowing objects in the boiler. The coatings would be peeled off faster and faster once they are breaking. Composite thermal spray coatings of double-effect,corrosion, both abrasion resistant anticorrosive, is a good solution to high temperature corrosion and wear problems simultaneously.
