How to Pass a 100-Hour Salt Spray Test for Electroless ...

May 01, 2017 · As EN baths age, the stress of the EN deposit generally becomes more tensile. High tensile stress values can lead to more brittle deposits and sometimes cracking, which can lead to premature salt spray failures or bad adhesion. Deposit Thickness. The minimum thickness that will give consistent values in salt spray tests for EN is 0.5 mils.

Understanding Corrosion and Salt Spray | Products Finishing

Jan 01, 2016 · If you wanted some chromated zinc-plated parts to pass 96 hours in salt spray to white rust, the exact same part is expected to reach anywhere between 61 and 131 hours if placed in two different chambers. So, unless your part averages 150 hours in salt spray, on average, half your parts will fail and half your parts will get to 96 hours and above.
