Professor Zhu Hongbin has long been engaged in fundamental and engineering research on additive manufacturing and remanufacturing of high-strength aluminum alloys, alloy steels, and other materials used in high-end equipment. He has developed independently patented powders, forming processes, and repair technologies for high-strength aluminum alloys with a strength grade of 550–600 MPa for additive manufacturing. He has also developed a series of powders for additive repair of high-strength, high-toughness, long-life shafts, and designed a thermal-mechanical synchronous hybrid additive manufacturing process and equipment. These technologies have been applied in the additive manufacturing and repair of high-strength aluminum alloy motor end caps, diesel engine thin-wall oil seals, and alloy steel motor shafts and axles. He has proposed mechanisms and methods for crack inhibition and synergistic control of strength and toughness in additive manufacturing microstructures. The thermal-mechanical hybrid repair process and equipment for shafts he developed have achieved the first domestic application. In addition, the Cr7C3 and TiB2 in-situ self-generated metal-ceramic coating materials independently developed by his team have been applied for the first time in China to the surface coating of medium- and large-sized diesel engine piston rings. These achievements provide technical support for the remanufacturing repair and strengthening of high-performance components in high-end equ
