I cant help you sorry

Gumby,

Could cryogenic treatment and coatings work together to build a better tool?

Depends on the tool/application but generally speaking if the material responses favorably to cryogenic treatment then it will make a better substrate for wear resistant coatings. In short to answer your question: "Yes".

Don't get me wrong cryogenic treatment has a lot of applications. End mills just are not one of them where it is economical to do because of the performance of coated carbide. I think the largest users of cryogenic processing is gear manufacturers. I can also see this being of value to various bearing types.

The thing is you really need to understand the process to be able to do something useful for your clients. If you simply treat their item and take their money then you are missing out on a lot of potential repeat business. This is because some things will have no perceivable change so the client will think your process does not work (ie they won't ever come back).

If you are dead set on treating tools then focus on drills for example where HSS is still common. Just understand that in a rigid setup a carbide still will outperform a HSS drill hands down no matter what you treat or coat it with.

Thanks for the pointers Gumby. Do you have any sites with more information on coatings? Thanks.

Gorilla Mills catalog and go to page 51.

Otherwise seaching PVD or CVD coating should result in several hundred thousand hits. Top 10 should give you some basic information about the various coatings available and what application they are bested suited for.
