摘要

针对电站锅炉受热面因高温氧化而导致的爆漏

采用Q235低碳钢作为基体

分别喷涂PS45、FeCrAl、4Cr13等3种涂层

与没有涂层保护的钢研102钢管材进行抗高温氧化试验。结果表明

没有涂层保护的钢研102钢抗氧化能力较差

而Q235低碳钢经电弧喷涂保护后其抗氧化性能得到大幅度的提高。其中

PS45涂层中由于Cr、Ni含量较高

在试样表面可持续形成结构致密、性质稳定的Cr2O3保护层

具有优异的抗氧化性能

使试样得到充分保护。

Abstract

Directing against tube-burst and leakage problems of heating surface in utility boilers due to high-temperature oxidation

taking Gangyan 102 steel as the base metal

three kinds of coatings

namely PS45

FeCrAl

and 4Cr13

have been sprayed respectively

a test of high-temperature oxidation resistant coatings on heating surface being carried out.Results show that the oxidation resistant capability of Gangyan 102 boiler tube material proper without coating is worse

after spraying protective coating by using electric arc

the oxidation resistant behavior of 102 steel has been enhanced by a big margin.In three kinds of coatings

owing to Cr and Ni content in PS45 coating is higher

a protective coating of Cr2O3 with compact texture and stable behavior can be continuously formed on surface of the specimen

boasting outstanding oxidation resistant behavior

making the specimen to be fully protected.
