Our laboratory suites include complete chemical testing and analysis equipment for a wide variety of industries, using a unique combination of analytical capabilities, equipment, technical expertise and quality systems. Specific focus on coating characterization and failure-analysis capabilities allow an in-depth insight into our coatings: understanding the make-up and chemical balance enables our technical teams to not only identify but also solve a variety of coating problems.
Our analytical capabilities provide the basis for a broad range of services, including problem-solving, failure analysis, formulation, chemical analysis, troubleshooting, consulting, experimental design and analysis, and independent laboratory studies. We also offer full analytical capabilities including deformulation (reverse engineering) and contaminant identification.
Abrasion resistance is the process of rubbing away the surface of something; wear means to become thin and disappear after repeated use or rubbing. The abrasion and wear of metal occurs through friction – the contact causing wearing on the metal surface. As contact is made between mating metal parts this has an impact on the component surface, resulting in momentary welding of asperities (peaks). As each part continues to move, the welded asperities are ripped off, leaving behind pits.
XYLAN® coatings provide a thin layer of lubrication to prevent the asperities on mating surfaces from making physical contact with each other. The selection of the best dry lubricant, such as PTFE, moly, or graphite, for these applications depends primarily on the PV (Pressure X Velocity), atmosphere and operating temperature of the application.
Often, a Xylan coating provides enough lubrication to eliminate excessive wear. In most cases, friction and wear of the parts are reduced when one or both are coated with a dry-film lubricant. Also, the coatings serve as a thin cushion, spreading high point loads in bearing and reducing element fatigue.
Abrasion resistance and wear are the main cause of component failure in almost every industry – choosing the correct Whitford coating does not only extend the life span of a component but also improves performance.
