Design of a new test machine and investigation of wear properties of some metals

The wear losses are reason decrease of service life and economical damages. It must be carefully, when machine design especially. Because of the wear losses cannot be control, machine and equipment can be damaged, so time, material, and energy, and work can be lost. At this time, the wear losses at friction surfaces are due to energy losses, damage of size and tolerances of machine parts. So, wear is one of the important factors in choose of material.For this reason, in our study on this pin on disc machine wear speed, progression of wear part and value of the load will be control. On the other hand, it has been investigated wear behaviour of Cu, Ni and Ti based three different alloys by using this machine. It has been shown thatThe test results shows that this wear test machine it is enough as other wear machine.
