Hard Coatings For Steel

Hardcoat anodizing anodic oxide coating rockwell c scale rating of 60 70 corrosion electrical temperature resistance low friction coefficient modified hard coating also known as hard coat anodizing or hard anodizing is an electrochemical process that applies a corrosion resistant coating chemically bonded to the surfaces of aluminum and aluminum alloy parts or pieces.

Hard coatings for steel.

Thermal spray hard surfacing gives equipment and component parts substantially greater wear resistance even in extreme working environments and high cycle or continuous use applications. Duralar is a remarkable new class of nanocomposite ultra hard metal coatings applied by duralar coating systems duralar technologies is a global coating machines company that has created unique new families of advanced ultra hard metal coatings. Our steel coating options include. Plasma transferred arc hard surfacing.

Many of these new coatings blend metal and diamond based components to achieve exceptional toughness strength and a range of performance. You can apply it directly over rusted metal steel surfaces or existing paint with no sandblasting required. Submersible epoxy coatings also known as coal tar epoxy these coatings are our most resistant to abrasion chemicals and corrosion on concrete and steel. Especially in salt air marine environments.

With a 15 000 hour salt spray test astm b117 rating rust grip is therefore one of the most effective anti rust anti corrosion coatings. They can be immersed in salt water and fresh water. Almost twice as hard as concrete. Duralar hard coatings can be much thicker than conventional coatings and they actually contain clusters of diamond material giving them significantly greater hardness and wear resistance.

This is the coating of choice for production work in non ferrous materials because of its higher hardness and its ability to run at two to three times the speed of uncoated tooling. Carbon steel coatings can be used to rebuild or repair surface damage on many steel substrates bringing them back to oem specs while closely matching material properties. Our range of nanostructured coatings can be applied to a wide range of metallic substrates including stainless steels superalloys tool and carbon steels as well as nickel copper and cobalt based alloys and are a recognised replacement for hard chrome and cadmium plating ceramics and hvof tungsten carbides. With a surface hardness near 9 000 vickers cvd diamond coatings that have been grown onto the tools show 10 to 20 times better tool life compared to pvd coatings.

In addition duralar also has greater thermal stability than many other coatings. Stainless steel coatings provide exceptional wear and corrosion resistance and are ideal for dimensional build up of worn or damaged parts. Apply with a sprayer. From mining to steel production equipment designers and builders use specified hard coating surfacing technologies in key high wear areas.

Amorphous alloy coatings such as nistelle and hastelloy greatly improve temperature wear and corrosion resistance.
