Macrocracks in Hard-chrome layer!

2000

We are currently using HEEF-25 and we have a problem of macro-cracks in our chromium-layer! Normally HEEF-25 produces a lot of micro-cracks!

What could be the cause of this problem? Chlorides? Iron?.....

Sincerely

Dear Andy,

It is to my opinion nearly impossible to produce macrocracks in a hardchrome layer from HEEF-25C.

Are the cracks present "as plated" or after grinding?

A macro crack structure is very well possible after grinding. Most of the time the cause of the problem is the use of a hard grinding wheel in combination with unsufficient cooling during the grinding operation. Did you already contact the Atotech people? They should be able to help you.

Good luck and kind regards,
