Problems solved by technology

If laser cladding can be used to treat the working surface of the perforated plug, then the mechanical properties of the perforated plug can be ensured and the cost can be reduced. However, there is currently no metal powder specially used for laser cladding of the perforated plug, and other metal powders can be used. When the

Abstract

The invention discloses special nickel-based metal ceramic alloy powder for laser cladding on the surface of a piercing point. The special nickel-based metal ceramic alloy powder comprises the following compositions in percentage by weight: 10-11% of silicon carbide, 0.2-0.5% of carbon, 4-5% of calcium fluoride, 1-3% of silicon nitride, 1.5-1.8% of vanadium, 2-4% of silicon, 6-7% of ferrum, 17-19% of molybdenum, 15-16% of chromium and the balance of nickel. The special nickel-based metal ceramic alloy powder is specially used for laser cladding of the piercing point, the metal tissue compactness of the piercing point can be improved, so that the toughness, strength, heat resistance and oxidization resistance of the piercing point can be improved, and the manufacturing cost of the piercing point can be lowered.

Description

technical field [0001] The invention relates to an alloy powder, in particular to a nickel-based cermet alloy powder specially used for laser cladding on the surface of a perforated plug. Background technique [0002] Laser has the characteristics of high brightness, high directionality, high monochromaticity and high coherence, and is now being used in more and more fields. Laser cladding is one of the surface treatment technologies. In a nutshell, the principle of laser cladding is to use high-energy laser beams to irradiate the surface of metal materials, the surface of the substrate is melted rapidly, the liquid metal forms a small-scale molten pool, and new powder materials are filled at the same time. , the original metal material is mixed with the added powder to form a new layer of liquid metal. After the laser beam passes through, the liquid metal layer is rapidly cooled to form a solid cladding layer on the metal surface. The perforated plug is a key tool in the ...
