Significant progress has been made in the surface treatment technology of investment casting metal impellers. The new composite plating process enables the impeller surface hardness to reach over HRC60, increasing wear resistance by 3 times. This treatment technology is particularly suitable for water pump impellers conveying media containing solid particles. The investment casting process provides an ideal substrate for surface treatment, and its uniform microstructure ensures strong coating bonding. Market feedback shows that investment casting metal impellers with special surface treatment are in high demand in mining, wastewater treatment and other fields.
In addition, the new composite plating process not only significantly improves hardness and wear resistance, but also greatly enhances the corrosion resistance of the impeller surface, effectively extending the service life of the equipment under harsh operating conditions. This technological innovation benefits from the deep integration of materials science and surface engineering technology, marking a solid step forward for China's metal impeller manufacturing industry towards high performance and high reliability. Especially in the face of increasingly stringent environmental protection requirements and the dual challenges of improving industrial production efficiency, this investment casting metal impeller with innovative surface treatment, with its excellent durability and adaptability, has become a key component in promoting the green transformation and energy saving and emission reduction of the water pump industry. In the future, with the continuous maturity of the technology and the expansion of its application range, it is expected to show broad application prospects in more fields such as petrochemicals and marine engineering, contributing to the sustainable development of the social economy.
