| Abstract: | In view of the protection of boiler tubes, high temperature oxidation resistance, hot corrosion resistance and coating hardness of three new cored spray wires were studied by measuring oxidation weight increase, corrosion weigh increase with salt coating and surface hardness of the coating. Results show that the new cored spray wires have excellent high temperature oxidation and hot corrosion resistance, which are improved with Cr content increasing. Moreover, GLl spray wire not only has above-mentioned properties, but also has higher surface hardness. |
