|Corrosion Resistant Coatings|
Nothing is harder on parts than heat and friction which are the biggest causes for corrosion in most engines. Heat will thermally fatigue a piece of metal to the point that it will start oxidizing and falling apart. But what about other types of corrosion? Corrosive elements such as salt and acid can damage your parts as quick as anything if not treated with the proper application.
HPC has a line of products that have been tested, by third parties, to show that even the harshes conditions can be guarded against with a good coating. Check out the products below or call to talk to a knowledgeable tech who will be happy to help you find a solution that is right for you. HPC has onsight engineers that work day in and day out helping companies save money with intelligent solutions.
Often mistaken for rust, thermal fatigue/oxidation is a problem caused by cyclical temperatures and hot gas impingement. HiPerCoat retards oxidation and heat buildup even at temperatures up to 1,600° F. Bonded onto steel, it extends component survivability by over 100-times.
Field performance proven HiPerCoat has the unique ability to protect components against corrosion even when the coating is damaged. It was the first coating of its kind in the automotive industry and remains unsurpassed in quality. HiPerCoat meets U.S. military specification MIL-C-81751B for metallic-ceramic coatings, has FAA approval on several models of aircraft, and is OE specified by auto, truck, motorcycle, and powersports equipment manufacturers.
HPC’s coating H01 was tested to see how it would stand up against other methods of protection when it came to Salt Corrosion. As anyone near the coast or who has had to drive on salt crusted roads in the winter can tell you, salt does major damage to car and engine parts.
A third party, Sherry Labs of Tulsa, Oklahoma, recently conducted testing to determine if HPC/H0l coating would meet 3000 hours of a standard ASTM B 117 salt spray testing. All pieces tested were exposed for 3024 hours without any indication of rust or corrosion.
As you can see compared to many other types of coating, HPC’s coating outlives and protects longer.
A test to see how corrosion resistance to acids was done on aluminum using HPC’s S04G. It is an extremely durable coating with outstanding chemical resistance. It was successfully tested and proven to eliminate exfoliation/corrosion on aluminum that is subjected to acids, elevated temperatures and condensation/moisture.
The coatings unique ability to exhibit these properties has allowed its application on many OEM diesel EGR components. Another unique benefit of the coating is its resistance to thermal shock, abrasion and water swell.
The coating has outstanding post formability and may be used on flange surfaces without effecting the proper seal of the components. Variation in thickness have shown not to effect the corrosion barrier of the coating.
A minimum thickness is required to protect the substrate metal. Testing procedures to simulate actual conditions/environments that are encountered, HPC tested by the following means: Subject the component to 24 hours of constant acid drip. Samples are to then be micro-sectioned and inspected for integrity of coating. • No exposed substrate shall be accepted.
The HPC coated with S04G and the competitive coating were then micro-photographed (micrographed) after a 24 hour testing period. Failure was based upon whether or not the acid ate through the coating and exposed the aluminum. S04G was successful in keeping the acid out while the competitions failure was evident even before the micrograph was taken.
