A dishwasher is a mechanical device for cleaning dishware and cutlery which have received a lot of attention these days. This device can improve washing process in addition to water and energy consumption reduction. Different kinds of dishwashers have come on the market. The countertop dishwasher is one of its kinds which has less capacity and occupy less space in comparison to freestanding type. These types of dishwashers occupy less space. Unlike manual dishwashing, which relies largely on physical scrubbing to remove soiling, the mechanical dishwasher cleans by spraying hot water, typically between 45 and 75 °C (110 and 170 °F), at the dishes. Due to the permanent presence of detergents and water in the washing process, the body of the appliances should be resistant to corrosion. To this end, appropriate coatings have been developed to protect metallic bodies of these appliances. Conversion coatings are one of them which include chromate conversion coatings, phosphate and zirconium conversion coatings on steel, and anodizing. The main applications of them are corrosion protection and using as an undercoat of organic and inorganic colors. Among these kinds of coatings, zirconium based ones possess advantages. No need to temperature increase, activation and the use of distilled water in their coating processes, coating’s process time and cost reduction, absence of some elements such as nickel, chromium, phosphate and production of ultra-thin (nano meter) coatings and achieving to better corrosion resistance and better adhesion of colors to substrate are some of them. Coatings with nano meter thickness are used in this product to achieve better corrosion and adhesion properties.
