Food quality largely depends on the processing equipment. Therefore, major requirements are imposed for resistance to wear and corrosion of the installations for the food industry, because they work in rather difficult conditions: high speeds, aggressive environments, high temperatures. Currently there is an increased necessity for reducing and control the wear and corrosion. Some of them are: prolonging the lifetime of equipment and bio-systems, the streamlining of engines and devices, the creation of new and advanced products, conservation of scarce resources, saving the energy and increasing the safety.
