Problems solved by technology

[0002] At present, on the surface of many anti-wear equipment parts, mechanical bonding is adopted, and high-chromium alloy liners are inlaid. The working conditions are very harsh, and the equipment is required to have both the reliability of fracture prevention and the wear resistance of wear resistance. The operating life is generally 8000-12000 hours. The worn wear-resistant liner grinding rollers and grinding discs must be repaired or replaced.

Embodiment Construction

[0033] A production process for compounding high-chromium alloy ceramic particle composites on the surface of wear-resistant parts, comprising the following steps in sequence:

[0034] (1) Preparation of high chromium alloy ceramic particle composite grid:

[0035] Melt the high chromium alloy and place it in the ladle, add sintered and crushed alumina and / or zirconia particles with a particle size of 80 to 100 mesh in the ladle, stir and mix, inject the mixture into the grid sand mold, and then Cooling and taking out to obtain a high chromium alloy ceramic particle composite grid 1;

[0036] (2) Fix the high-chromium alloy ceramic particle composite grid 1 on the modeling surface, and cast the machine part, so that the high-chromium alloy ceramic particle composite grid is fixed on the machine part surface.

[0037] The added amount of the alumina and / or zirconia particles is 30%-40% by volume.

[0038] The alumina and zirconia particles are particles with a content of 95% ...

Abstract

The invention discloses a manufacture technology for compositing a high-chromium alloy ceramic grain composite on the surface of a wear-proof machine part, which comprises the following steps of: preparing a high-chromium alloy ceramic grain composite grid; fixing the high-chromium alloy ceramic grain composite grid on the shaped surface; and casting the machine part, so that the high-chromium alloy ceramic grain composite grid is fixed on the surface of the machine part. The manufacture technology organically combines the wear-proof resistance of the ceramic grain material with the mechanical performance of the high chromium alloy, can manufacture the composite material with good rigidity, impact resistance and wear resistance, can manufacture the composite material with the shape of grid, can manufacture the composite with various shapes and sizes such as taper, arc, arc and the like, secondly casts the super-hard netty composite to form into the wear-proof product as required, and can effectively meet the requirement of the work condition of crushing resistance and wearing resistance of the equipment.

Description
