Study on HDPE Components with Abrasive Wear in Rotation for Industrial Applications- A Review

Abrasion wear is one of the most common failure mechanisms of moving machine elements. Because of their mechanical and tribological ability, engineering polymer composites can be chosen to replace metal parts in certain applications (e.g. bearings). Increasingly newer polymer composites are appearing and data on their tribological behaviors are incomplete, it is not so easy to choose from this wide wide selection of choices (mechanical properties, price, etc.). In the present study two groups of polymer composites In many fields of industry, abrasion and erosion processes are dominant wear mechanisms that reduce lifetime of costly machine parts. Wear resistance against abrasion and/or impact or the ability to withstand other complex mechanical actions are often required. In order to quantify the specific properties of material that are applied in such fields, several test methods are in use. A certain discrepancy can be seen between the systems approach and the aim to get information about suitability of materials for practical applications simply from specific material tests. This paper gives an overview over a selection of relevant test equipment and procedures. In addition, some examples are given for advanced studies on materials behavior combining tribological test, material analyses respectively materialography and mathematical methods in order to support – for selected cases.
