Proprietary commercial anodizing processes?

1998

Hello,

It is greatly appreciated if anyone can provide me with any information or data regarding the Alpha, Alzak, Imperv-X, Mod Martin, and Anodal EE anodizing processes, such as perfomance (consistency, problems, etc.), operational conditions (concentration, voltage, current density, temperature, agitation, etc.), and the properties of resultant anodic films (hardness, abrasion resistance, corrosion resistance, etc.).

Thanks!

There is some information and references quoted in The Surface Treatment and Finishing of Aluminum and Its Alloy.

Authors are Wernik, Sheasby and Brace. It is a two volume set. Considering who you work for, I would assume that you already have it in someones library.

You have asked for such an extended list, I rather doubt if anyone is going to do the homework to offer much help. You have basically asked for the recorded history of hardcoat.

Sir,

I run 2 large anodize / hardcoat plants and I am familiar w/ the terms you ask about:

ALPHA - is a proprietary hardcoat system - we looked at it years ago & didn't see much potential - but it may have changed and it may suit some better than others - I have a friend in Philadelphia PA who uses it.

ALZAK - WE DO THIS - is chemical brightening of aluminum as a pretretment beofre anodize - The fumes are very bad and not many anodizers do this

IMPERV-X - WE HAVE THIS - is also a proprietary hardcoat system . It works wondeful for hardcoating high copper alloys (i.e., 2024)- the company that developed this system has been out of business for many years & it is very hard to get parts for this system.

MOD MARTIN - WE HAVE THIS - I would consider this a normal or convetional low temp hardcoat system.

ANODAL EE - WE HAVE THIS - This is a chemical additive used for hi temp hardcoating - we run it at about 60 deg f. The coating it produces meets the mil-spec 8625 Type III, BUT the coating comes out very light in color so some customers don't think it is hardcoat. It gives you a light enough backround that you can easily dye it decorative colors.
