Research on Mould Filling and Solidification of Titanium Alloy in Vertical Centrifugal Casting

Characteristic of Interface Bimetal Aluminum-Copper for Bimetal Bushing Produced by Centrifugal Casting

“…The two metals complement each other in mechanical, chemical, and physical properties [11]. Bimetallic composites can be made by gravity casting [12] or centrifugal casting [10]. The manufacture of bimetallic composites by casting produces a cohesive compound and diffusion of the metal interface during pouring, resulting in a high bond strength [13].…”

“…One of the current developments of bimetal is to manufacture bushing products. Making bushings using the gravity casting method will produce low-density products with cast defects [12]. Meanwhile, the manufacture of bushing by centrifugal casting will create products with accurate dimensions, smooth surface, less gas porosities, and faster freezing [2].…”

Bonding of Interface Bimetal Aluminum-Bronze for Bimetal Bushing Produced by Solid Liquid Method

“…The two alloyed metals complement each other in their physical, mechanical, and chemical properties [12]. Bimetal can be manufactured by centrifugal casting [10] or gravity casting [13]. The manufactured by casting forms a metallurgical bonding at the interface and diffusion of the two metals during pouring, which results a high-strength bond [14].…”

“…One of the bimetallic applications currently being developed is the manufacture of bushing products. The bushings have a low density caused by cast defects [13] when manufactured by gravity casting. The bushings made with centrifugal casting will obtain products with less porosity, smoother surfaces, precision dimensions, and faster solidification [2].…”
