(1) The process is simple and the cost is low.
(2) Refining grains.
(3) Control parameters such as centrifuge speed, pouring temperature, mold preheating temperature, mold coating agent thickness, cosolvent, etc., so that the strength of the bonding interface can reach the standard and reduce major defects such as internal shrinkage cavities and slag inclusions.
(4) Good formability and easy to obtain castings with compact structure and excellent mechanical properties.
(5) It has incomparable advantages in the manufacture of ring parts such as metal matrix composite pipes and sleeves.
{6) The overall composite material has good wear resistance, high hardness, high toughness and long service life.
(7) It has incomparable advantages in the manufacture of ring parts such as metal matrix composite pipes and sleeves.
(8) Continuous alumina fiber reinforced aluminum matrix composites can be prepared by casting. The main difficulty with the casting method is wetting the alumina fibers. After 15 years of research, the casting preparation process of continuous fiber reinforced metal matrix composites has matured. Such as pressure casting. Squeeze casting. Ultrasonic impregnation and interface chemical reaction, etc. Compared with other preparation methods (such as diffusion bonding, physical or chemical vapor deposition, etc.), the cost of casting method is lower
