SURFACE TECHNOLOGY Blade life was two hours, and the production line had to be shut down to change blades. A coating developed by Surface Technology doubled the blade cost but extended blade life to eight hours. The net result was a 50 per cent overall cost reduction. On top of these equipment-related savings, the longer life meant blades could be changed at the end of shifts, leading to higher production runs per shift and lower scrap biscuit and caramel costs. It is also worth noting that smaller cookware items benefit from coatings in the same way as larger equipment. Non-stick performance is totally dependent on the coating’s useful life, which means that more durable, higher-cost options more than pay for themselves in better performance and longer life. Medical device manufacturing Surface Technology’s applies FDA-approved coating systems on medical devices and equipment where surface release and low friction are key requirements. In these applications, which often involve high-cost assemblies, a quality surface coating drives down wholelifecycle costs by prolonging equipment life and reducing scrap. One example is the use of non-stick, easyrelease coatings on equipment used to manufacture superconducting magnets for MRI scanners. The niobium wire wound coils that enable superconductivity at very low temperatures are extremely expensive. You can reduce scrap rates by coating the equipment designed to encase the magnet and preventing movement when the magnet is activated. As a result, the added coating cost lowers whole-lifecycle costs. Automotive industry A primary requirement for this industry is to increase the service life of components. This might be achieved by improving corrosion resistance, wear resistance, or reducing friction and, of course, in one of the world`s most competitive industries, it also has to be cost-effective. With the growing emphasis on lightweighting, aluminium is an increasingly important material for the automotive industry. Surface coatings protect aluminium components from corrosion, thereby facilitating the lower vehicle weights that improve fuel consumption. By taking positive design measures and choosing the right materials and coatings, it is possible to create a lighter and lower-cost solution for vehicle manufacture. Friction reduction is critical to improving engine performance. Engine block cylinders are a major target for friction reduction due to relatively high engine speeds. One such solution for this issue is plasma coatings used on engine block cylinder bores. Testing has found that it is able to replace the pressing, shrinking and casting-in of cylinder sleeves and the use of expensive, nickel containing galvanic plating processes. With plasma sprayed bore coatings, a cylinder case will only be honed when required from operation (such as with debris ingestion). Plus, the need for a bore hone with each rebuild will be eliminated, 192 2017 - 2018 read online: www.surfaceworld.com SURFACE TECHNOLOGY Blade life was two hours, and the production line had to be shut down to change blades.
