Improving resistance against corrosive environments 14 February 2022

Atotech, a global supplier of speciality surface finishing solutions, has announced the global launch of its innovative high phosphorus electroless nickel process, Nichem® HP 1170.

Atotech says Nichem® HP 1170 provides superior corrosion resistance in acidic environments, especially those containing nitrates, chlorides, and sulfides with a deposit consisting of >10% phosphorus.

“We are committed to finding the best solutions to improve the corrosion protection offered by electroless nickel coatings for highly corrosive environments,” says Shakeel Akhtar, global product and business development manager of wear resistant coatings at Atotech. “With Nichem HP 1170, we truly believe we have achieved the highest possible performance in this goal. Nichem HP 1170 represents the next step in the evolution of electroless nickel processes; it meets all of the stringent demands of the industry.”

Nichem HP 1170-plated deposits are bright in appearance, have excellent wear resistance, and boast a plated hardness of up to 620 HV0.1 which increases to 930 – 1080 HV0.1 after heat treatment. Furthermore, the process’ deposits exhibit high-levels of corrosion resistance. Nichem HP 1170 is a sustainable process - it is lead and cadmium-free and meets the highest standards of environmental compliance, including ELV, RoHS and WEEE.

Nichem HP 1170 provides excellent bath stability and is a self-regulating formulation with respect to pH. Deposits remain compressively stressed up to 6.5 MTO, offering economic, quality, and operational benefits. In addition, Nichem HP 1170 has a wide working window for low and high bath-loading scenarios and allows for fast plating rates.

Nichem HP 1170 is suitable for a wide variety of applications in the automotive, oil, gas, and chemical industries as well as for offshore construction, agriculture, and heavy machinery – where outstanding corrosion resistance is required.
