Abstract
The cylinder block with an integrated cast iron cylinder is an efficient and useful design in reducing the weight of the engine, reducing the time and cost of machining and removing the pollutants caused by using cast iron. By modeling the Alfin process, which is used in the production of a piston with an integrated cast iron ring, a research was conducted on the strength of the bond between the aluminum cylinder block and the cast iron cylinder with a porous outer surface, considering this process to create a bond between two different materials in composite casting. The cast iron part and the aluminum cylinder block should be adopted in the most optimal state of the parameters of the production process, such as the temperature of the molten bath and the appropriate immersion time, and the composition of the elements of the molten bath, in order to create a reliable bond. Another factor influencing the establishment of this bond is the coating on the cast iron part before immersion in the melt. It is aluminum to facilitate metallurgical and mechanical bonding. In this article, the effect of copper coating by electroplating method and flux coating on cast iron cylinder has been investigated by performing a tensile test on the sample. The results indicate a higher bond strength between the cast iron cylinder and the aluminum cylinder block in the sample of the cast iron cylinder coated with copper element by electroplating method.
