Abstract

The invention belongs to the field of metal materials, and particularly relates to a nickel-based alloy material for hardfacing and a preparation method thereof. The nickel-based alloy material for hardfacing comprises the following raw materials in parts by weight: 0.05%-0.15% of C, less than 0.5% of Si, less than 0.5% of Mn, 20%-24% of Cr, less than 0.01% of S, less than 0.01% of P, 8%-10% of Mo, 10%-15% of Co, less than 3.0% of Fe, 0.8%-1.5% of Al, less than 0.6% of Ti, less than 0.5% of Cu and the balance being Ni. According to the method, surfacing is performed by adopting a plasma transferred arc surfacing technology to prepare a wear-resistant nickel-based alloy surfacing layer. The nickel-based alloy material provided by invention effectively solves the problem of poor wear resistance caused by air holes and cracks generated in an application process of surfacing nickel-based alloy materials in the prior art, and has a great commercial prospect.

Description

technical field [0001] The invention belongs to the field of metal materials, in particular to a nickel-based alloy material for wear-resistant surfacing welding. Background technique [0002] The working state of mechanical tools must be very stable and reliable. Once abnormal failure or early failure occurs, it will bring significant economic losses and even serious safety accidents. However, mechanical tools in harsh working environments usually suffer from very serious wear and tear In drilling engineering, mining engineering, construction engineering and geological engineering, there are more and more parts of drilling tool products that need to be wear-resistant enhancement or wear-resistant protection, and the requirements for wear-resistant performance are also increasing. higher. [0003] In order to make the mechanical tools operate effectively within the design life, researchers have successively developed strengthening processes such as remelting strengthening, ...
