In the production process of aluminum alloy castings, especially in the process of aluminum alloy castings and powder metallurgy manufacturing, a large number of micropores, sand holes, cracks, etc. are inevitably generated due to factors such as residual pores and crystal shrinkage. Micropore leakage can bring hidden dangers to the application of mechanical equipment.
Even for applications without pressure regulations, internal corrosion may occur due to electroplating, spraying, and surface treatment solutions such as electroplating and acid entering the interior of the casting, shortening the service life of the parts. The presence of micropores can cause bubbles or unevenness in the surface coating, electroplating, and other processes. And the damage to aluminum castings through infiltration is almost zero, greatly reducing costs and fully utilizing limited resources, resulting in products that are more compliant with regulations.
The penetration effect and effect of aluminum alloy castings are very obvious. On the one hand, through this solution, aluminum alloy castings can have compression resistance, sealing, and corrosion resistance functions, and the micropores of the product can be filled with impregnation solution for sealing, blocking connected or disconnected micropores, and preventing internal corrosion.
On the other hand, it can be pre processed for generation, filling concave seams, and preventing discoloration, corrosion, peeling, and expansion; Improving the cutting performance of aluminum bronze castings, filled with metal internal penetration, can increase tool life and reduce processing costs.
At the same time, it also helps improve the physical strength and insulation of aluminum alloy castings. The permeate fills and blocks the internal gaps of micropores, improving physical strength and thinning the designed product; Blocking internal cracks can increase the resistance value of protective functions.
