What is the Salt spray test to check corrosion resistance of chrome plated piston rod
The salt spray test is a standardized test method used to check corrosion resistance of chrome plated piston rod . It involves a hard chrome bar sample being placed in a chamber containing a fine mist or aerosol of salt particles, representing natural weather conditions. The damage to the sample is measured visually and compared against other samples, with the results being reported as equivalent "hours at" exposure. Salt spray testing is used to assess the durability of finishes and coatings on hydraulic cylinder rod surfaces. The test can be used to evaluate the impact of different exposure conditions, such as humidity and temperature, on a coating's ability to resist corrosion. It is also used to compare the performance of different coatings and finishes. There are three kinds of salt spray test: Neutral Salt Spray Test (NSS), Acetic Acid Salt Spray test (AA SS) and Copper Accelerated Acetic Acid Salt Spray test (CA SS）,, among which the most widely used test
