Abstract

The problems faced by entrepreneurs in the field of transportation at this time is a problem the availability of spare parts and spare parts at high cost. Engine prime can be maintained if, is coupled with maintenance and replacement of spare parts on regular basis or the improper use. Based on the problem, research on the field of innovation spare parts for quality mass transportation, reliable and inexpensive need developing. One problem is the wear of piston causing damage. To reduce consumption of aluminum need to require recycling of aluminum. In this research the focus of the problems is to study about the material characterization of piston and piston prototype development based waste Piston. The experiment was conducted on the pouring temperature variations of 700, 750, 800oC, the piston alloy compositions are: 75% waste piston + 25% ADC 12, 50% waste piston + 50% ADC 12, 25% waste piston + 75% ADC 12 and as a control waste piston pure and ADC 12 pure. Material characterization of the piston prototype was conducted including the chemical composition, microstructure, hardness, porosity and roughness. The results of prototype material and development of piston prototype based waste piston shows best with 64.5 HRB hardness, low porosity 4.613 and roughness before machining is the product 1.58 achieved of the composition of 25% waste piston + 75% ADC 12 with the pouring temperature of 700oC. Keywords: Prototype of the piston, the piston of waste material, pouring temperature, the former pure piston.
