Typical hard chromium deposits are micro-cracked with a crack density of 800 - 1,200/lineal inch. Micro-cracking is desirable as it retains oils and lubricants that reduce friction in service and prolong wear life. A properly micro-cracked deposit is also harder and stands up to corrosive environments better.
