Kovar alloy was machined and prepared as half bushes with diameter 1.6cm and length of 1.5 cm. Many specimens were prepared and subjected to wear testing system under lubricated condition. The tests were carried out under different condition such as sliding speed of 750rpm and fixed lubricant type and under variable conditions such as sliding time and normal loads. Weight loss and wear rate were determined for all samples and under different conditions. Kovar debris suspended in oil lubricant and placed in special container and subjected to X-Ray Fluorescence system to determine the quantitative and qualitative analysis.
