Problems solved by technology

A guillotine generally includes a bottom groove and a knife. One end of the knife is hinged on the bottom groove, and the other end has a handle, which can be used to cut hard objects such as metal sheets. After a long-term use of the guillotine, the blade of the guillotine is prone to wear, chipping, etc. defect

Abstract

The invention discloses a special cobalt-base metal ceramic alloy powder for guillotine laser cladding, which comprises the following components in percentage by weight: 11-13% of titanium carbide, 0.1-0.4% of carbon, 4-6% of calcium fluoride, 1-3% of silicon nitride, 6-9% of iron, 5-7% of chromium, 2-4% of zirconium, 1-3% of vanadium, 2-4% of silicon, 0.8-1.2% of manganese and the balance of Co. The cobalt-base metal ceramic alloy powder is specially used for guillotine laser cladding, reduces bubbles, cracks and shrinkage void defects on the cladding layer, and enhances the hardness, strength and shock resistance of the guillotine.

Description

technical field [0001] The invention relates to an alloy powder, in particular to a cobalt-based cermet alloy powder specially used for laser cladding of guillotine knives. 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. A guillotine generally includes a bottom groove and a kn...
