Properties

Salt spray testing is an accelerated corrosion test that produces a corrosive attack to coated samples in order to evaluate (mostly comparatively) the suitability of the coating for use as a protective finish. Mostly, the salt water contains 5%wt salt and 95%wt distilled water. PH of the solution is 6.5-7.2, spraying pressure is 0.83- 1.24 bar and the temperature of the exposure zone of the salt spray chamber is approximately 35 0C. According to ASTM B117 – 16 standards, coatings with the grade of 10 have the pest condition and 0 with the worst condition. Nanometric conservation coatings lead to better corrosion resistance. Accordingly, samples were scratched base on ASTM D1654-16 standard at first and then their corrosion resistance were evaluated by ASTM B117 – 16 “Standard practice for operating salt spray”.

Manufacturer's Description

Nowadays, the washing machine is one of the main requirements in every kitchen. This device is used to facilitate washing and drying of clothes and includes different kinds. The top load washing machine is one kind of them which is smaller in comparison to front load ones and has less complexity. Clothes can be added during washing process in this kind of washing machines. Generally, Due to their permanent exposure to detergents and water which may cause corrosion, coatings such as conversion ones have been developed. Conservation coatings are coatings for metals where the part surface is converted into the coating with a chemical or electro-chemical process. Examples include chromate conversion coatings, phosphate and zirconium conversion coatings on steel, and anodizing. Conversion coatings are widely used to protect metal surfaces against corrosion. These coatings have interesting appearance which makes them interesting for decorative applications and because of their good surface absorption properties; they can be colored with organic and inorganic paints. On the other hand, conversion coatings have engineering applications due to their corrosion protection properties and decorative application due to their surface properties. Zirconium based coatings have major advantages over their phosphate based counterparts which include absence of some elements such as nickel, chromium, phosphate, no environmental pollution, achieving to better corrosion resistance and adhesion properties as some results. Top- load washing machines are smaller and less complex in comparison to front-load ones. Clothes can be added during washing. Nano metric conservation coatings are used to get better corrosion and adhesion properties in these appliances.
