Black thin film coating

A new black thin film coating – TriCem 3,8000 – developed by the Armourcote division of Surface Technology plc, is reported to provide corrosion and wear resistance that dramatically exceeds the performance of zinc, zinc alloy and electroless nickel plated finishes in thin film coating applications, where high surface durability and the optimum life of components are primary requirements.

Described by the company as “the next generation in black metal finishing technology” TriCem 3,800 claims a high bond strength and adheres to a wide range of substrates, including all steel alloys, sintered metal, aluminium, cast iron, brass and copper. It gives a film thickness of less than 20m and is available in WEEE/RoHS and ELV compliant versions. It has a smooth, lubricious and hydrophobic surface and, during rigorous testing, has been reported to exhibit more than 2,000h' salt spray corrosion resistance to white corrosion. According to Surface Technology, Tri-Cem 3,800 contains no cyanides, ammonia or arsenic, so also conforms to current environmental legislation.

“For optimum surface coverage, corrosion and wear resistance, this high performance thin film coating outperforms currently available alternatives,” says David Miller, Chief Operating Officer for Surface Technology – Armourcote. “We are confident that in most thin film coating applications – particularly in the aerospace, automotive and electronics sectors – TriCem 3,800 will achieve significant production benefits in terms of enhanced surface protection and reduced process times.”

Part of Norman Hay plc, Surface Technology plc, operating through its Armourcote division, is a highly regarded specialist in the application of high performance coatings and plated finishes, and has a 60-year history in the surface engineering industry. It has been closely involved in the development and introduction of many cutting-edge surface coatings for specific applications in all market sectors.
