coating technology
The latest volume of The MISUMI Voice talks about coating technology and I find it relevant to what we are learning in our course.
4 samples of linear bushings of different material underwent the complex corrosion test including 1 salt water spray test (5% NaCl, 35 C), 2 dry (at 60 C), and 3 wet (85% relative humidity at 50 C). The result is as follows:
As we can see, after 168 hours the first 3 samples have visible corrosion while the fourth one with Low Temperature Black Chrome plating (LTBC) seems unaffected.
In a crapshell, LTBC is a plating technology which uses electrochemical reaction below 0 C. The product has no hydrogen embrittlement, no tempering required, improved hardness/elasticity ratio, no frictional peeling and it's the most resistant and the most effective rust protection plating achieved by all conventional methods.
Sounds cool?

strange. how come stainless steel still rusts? from the Fe content in stell isit?
