Abstract
The cement industry is one of the essential industries in Iraq that has taken a wide range of attention in many applied fields, but this industry faces some technical and engineering problems. One of these problems may cause consumption sliding bearing used in the kiln rotary of the Kufa cement plant. In this study, the effect of Antimony as an alloying element on the wear resistance behavior of tin bronze alloys produced by die and sand mold casting technique was investigated. The alloying element (Sb) was added with a percentage of 3, 5, and 8 wt. %. Wear tests were carried out using pin-on-disc. In the wear test, the applied load and rotating speed were selected to be 10, 20, 30 N, and 250 rpm, respectively. The prepared alloys have been characterized using the SEM and XRD techniques. It was concluded that the loss of CuSn12 alloy produced by the die mold casting technique was lower due to its higher hardness and wear resistance increased in general with increasing the applied load. The tin bronze + 8 wt% Sb has more wear resistance than tin bronze +5 wt% Sb, tin bronze +3 wt% Sb, and tin bronze alloys.
