					<description><![CDATA[<p>IMPORTANCE OF BLOCK-ON-RING WEAR EVALUATION Sliding wear is the progressive loss of material that results from two materials sliding against each other at the contact area under load. It occurs inevitably in a wide variety of industries where machines and engines are in operation, including automotive, aerospace, oil &#38; gas and many others. Such sliding [&#8230;]</p>
