Coating overcomes hydrogen fuel problems
Adiamond-like coating is making a significant contribution to the development of the hydrogen powered car by providing coating technology to overcome serious lubrication problems.
Poeton Industries, a world leader in surface coating technology, is making a significant contribution to the development of the hydrogen powered car by providing coating technology to overcome the serious lubrication problems posed by the use of the gaseous fuel Explains Poeton managing director Colin John: "Lubrication, or rather the lack of it, was proving to be a serious problem for a major US manufacturer of hydrogen powered internal combustion engines, causing severe wear to valve stems

Filtration system eliminates hard chrome pitting
A three-year project to develop a low-effluent hard chrome plating plant has dramatically improved the quality of the hard chrome plating by introducing a high-pressure filtration system.
Powder coating plant is jointly funded
A jointly funded automated powder coating plant will guarantee a trailer builder an output of in excess of 50 towbars an hour, allowing the company to offer customers a two-day delivery.
"We were asked if we could provide a coating that would solve the problem and recommended Diamolith, a diamond-like coating (DLC) that has already proved itself in high performance automotive powertrain applications." Diamolith adheres extremely well to materials used in automotive manufacture including tool steels, high alloy steels, aluminium alloys, titanium, etc.
Examples of the vulnerable powertrain components that can be protected include pneumatic sleeves, gudgeon pins and piston rings, where Diamolith prevents micro-welding.
Colin John also quotes extreme examples such as the cam followers and front forks of the Hawk Kawasaki Suprbike.
Non-automotive applications include pharmaceutical tablet punch dies, stamping dies, gears and medical components.
Diamolith, which is produced using the plasma-assisted chemical vacuum deposition (PACVD) method, is extremely effective for coating high quality components with complex and varied shapes.
