The effect of sintering pressure on the wear behavior of bronze (85/15) alloys produced using hip method

In this study, a new material was produced using Hot Isostatic Pressing (HIP) method, upon which Co and Ni in different ratios were added into a CuSn-based (85/15) alloy. HIP method has very important advantages in that it allows pressure and temperature to be applied simultaneously during the process. In the study, constant sintering temperature of 800 °C, a constant sintering time of 15 min, and two different sintering pressures of 20 and 30 MPa were used. The sintering process was performed under a vacuum after the initial burning process. The produced samples were subjected to various metallographic processes as well as SEM and EDS analyses. Afterwards, wear test was carried out on the samples. The study investigated the effects of Ni and Co additions and the sintering pressure on the wear behavior. It was found that as the amount of Co and the sintering pressure increased, the wear resistance increased.
