摘要：
Stellite 6 is a superalloy primarily composed of cobalt, known for its exceptional resistance to corrosion and wear at elevated temperatures. The current investigation involved the application of a co-based Stellite 6 coating on SS 304 boiler heat exchanger steel using HVOF technology. The objective was to boost surface wear resistance against elevated temperature. Protective coatings are widely employed across various industries to enhance resistance to erosion and wear of engineering components. The corrosion behavior of coated and uncoated steel was assessed under various conditions, including impact velocity, impact angle, and time duration, using a high-temperature air-jet erosion tester. Microploughing, cracking cutting, and hard phase pull-outs were all erosion processes seen in the coatings. Among the samples that were tested, it was observed that the Stellite 6 coating applied on SS 304 exhibited the lowest erosion rate. This study aims to facilitate the selection and optimization of coating materials suitable for applications in industry that require enhanced resistance against erosion wear under high-temperature conditions.
