Armoloy of Western Pennsylvania offers wear coatings and dry lubricants [Diamond Chromium Coating (98Rc) which exceeds the boundaries of standard coatings, and Thin Dense Chromium Coating (78RC), a low-temperature, multistate surface finishing process] that will solve corrosion and wear problems, saving both time and money.
Unprotected surfaces of major ferrous and nonferrous base metals are subject to several forms of corrosion. Combined with fatigue, corrosion is the significant contributor to the breakdown of the metals. Corrosion is a natural process which reduces the binding energy in metals creating oxidization of the metal which weakness the metal and can cause structural damage. Even stainless steel is not immune to some forms of corrosion. Due to higher surface hardness, Armoloy XADC Coating and Armoloy TDC coating have a longer wear life than stainless steel. Armoloy plating is less expensive than other metals such as regular chrome or stainless steel and can therefore provide a relatively large cost savings, while at the same time increasing wear life.
Benefits of Armoloy Chromium Coatings
Armoloy's key technology can reduce the problems associated with severe corrosion. Even pitting, one of the most destructive forms of corrosion, can be avoided with the use of Armoloy's corrosion resistant coatings providing increased efficiency and a reduction in maintenance costs.
Unlike conventional chromium coatings, Armoloy's proprietary processes (both the XADC Diamond Chromium Coatings and the Thin Dense Chromium (TDC) coatings are not off-the-shelf products. They have been custom-engineered to provide a coating solution for problems associated with corrosion and wear abrasion. Chromium is a natural corrosion resistant product. Armoloy's superior coatings won't crack, chip, or peel. They provide an excellent solution for protecting nearly all ferrous and non-ferrous metals including common molding steels such as H-13, S-7, P-20, 420SS, A-2, D-2, and copper alloys such as Moldmax and Ampcoloy.*
Armoloy's high-durability coatings serve three main purposes:
They provide wear and abrasion resistance.
(Due to surface hardness and the micro-nodular finish.)
They provide lubricity, release, and friction reduction.
(Armoloy's nodular structure will substantially reduce friction, providing longer wear.)
They provide corrosion resistance (on tool steel, comparable to 440C stainless steel).
(Even in severe environments, Armoloy coatings resist corrosion and perform better.)
Armoloy's protective coatings will provide coating solutions that maintain corrosion resistance for many possible applications. Our Thin Dense Chromium coatings provide a standard plating thickness of .0001/.0003" per surface. However, in molding, the .000050/.0002" range is more realistic, given the tight tolerances that are the industry standard so they won't interfere with the working of industrial equipment, And, Armoloy's coating solutions also have FDA approval for food processing equipment. In the food industry, Armoloy's gear wear resistant coatings can provide an excellent solution for machinery faults due to corrosion.
Unlike traditional hard chrome, a thinner deposit of Armoloy's XADC or TDC coatings do not inhibit the coatings' efficiency, and may prevent excessive edge build.In addition, the hardness of the substrate metal is not an issue; the harder the base metal, the more effective the XADC (98 Rc and TDC (78Rc) coatings become, (i.e., common Rc hardness for tool steels to be coated is 45-55 Rc). Even in the case of copper alloys, where hardness cannot be dramatically improved, Armoloy's corrosion resistant coatings can provide protection against abrasive wear, without inhibiting the copper's thermal diffusion properties, making it an excellent coating solution for copper tubing.
Armoloy's coatings will also extend the life and improve the efficiency of rubber and plastic parts. Surface hardness is increased to 78 Rc with Armoloy and to 98 Rc with XADC-Armoloy coatings. Armoloy's wear resistant coatings can greatly reduce or even eliminate the problems associated with abrasion wear and corrosion that can impact your needs. XADC/TDC coatings can:
Reduce downtime associated with parts replacement
Lower equipment maintenance costs
Enhance durability and extend equipment life
And above all improve efficiency and save money!
*Titanium, zinc, and magnesium are not recommended for Armoloy coatings
