When powder metallurgy mould presses powder, the mould cavity is easy to be worn by powder particles, which affects the density uniformity of products. Dow laser cladding equipment adopts wear-resistant and bond-resistant coating, the adhesive force between coating and powder is low, it is not easy to stick, and the wear-resistant performance is excellent. When a powder metallurgy plant is producing high-precision gears, the traditional mould wear causes large fluctuation of powder compaction density, the product qualification rate is less than 75%, and the production cost is high. With the introduction of Dow laser cladding technology, a customized Tungsten Carbide composite coating was applied to the surface of gear die. The surface roughness of the cladding mould is reduced from Ra3.2 μ m to Ra0.8 μ m, and the friction coefficient with the metal powder is reduced by 60%, which significantly reduces the demolding resistance. The actual production data shows that the service life of the mould is increased 2.5 times, and the single maintenance interval is extended from 200 hours to 500 hours; The density deviation of gear products produced is stably controlled within ≤ ± 0.02g/cm ³, and the product qualification rate is increased from 75% to 92%. At the same time, due to the reduction of mold replacement frequency, the mold procurement cost can be saved by over 800000 yuan per year, and the production efficiency is increased by 30%, achieving the double breakthrough of cost reduction and efficiency improvement.
