Unparalleled corrosion protection and aesthetic finishes applied across precision stainless steel substrates.
Bridging electro-deposition science with sustainable industrial development.
Electroplating formulations such as the 6185 Alkaline Zinc-Nickel Plating achieve a targeted co-deposition of 12-15% nickel content. This specific phase composition yields an intermetallic coating layer that dramatically increases the wear and temperature limits compared to traditional pure zinc layers.
Adhering strictly to green-manufacturing initiatives, chemical baths like the 8315 Alkaline Cyanide-Free Bright Zinc Plating deliver excellent thickness distribution and high current efficiency without the severe ecological hazards associated with legacy cyanide formulations.
Deploying products like the ZN-318 Blue and 216 Trivalent Passivation guarantees compatibility with modern global environmental frameworks while forming a self-healing film resistant to white and red rust formation.
In modern global manufacturing ecosystems, high-corrosion environments demand target-oriented solutions. Our plating chemicals and finished coatings cover a broad spectrum of critical structural applications:

Direct, engineering-focused answers to core technical queries regarding zinc and nickel coatings.
Stainless steel exhibits high general corrosion resistance but is vulnerable to pitting and crevice corrosion in chloride-rich or marine environments. A sacrificial zinc or zinc-alloy coating provides cathodic protection, preventing localized pitting and resolving galvanic corrosion challenges when stainless steel parts contact aluminum structures.
Our 6185 Alkaline Zinc-Nickel Plating co-deposits a uniform 12-15% nickel phase, forming a high-performance alloy layer. This coating withstands temperatures up to 200°C and provides up to 1,200 hours of neutral salt spray resistance without red rust, outperforming standard zinc coatings.
Our research centers focus on hexavalent-free and cyanide-free chemical formulations. Solutions like 8315 Alkaline Cyanide-Free Zinc Plating and 216 Trivalent Passivation eliminate toxic heavy metals and cyanide compounds, facilitating smooth international compliance audits.
Electroless Nickel coatings (like our HITEC EN 6713 and 6786 series) are auto-catalytic chemical deposits that provide uniform thickness over complex geometries. High phosphorus options (10-12% P) deliver exceptional chemical resistance, while low phosphorus versions (1-3% P) offer high hardness and excellent wear resistance.
Hydrogen embrittlement is a concern for high-strength steel substrates during acid cleaning and electroplating. We mitigate this through cyanide-free alkaline plating chemistry, controlled current density profiles, and prescribing a prompt post-plate baking cycle to release absorbed atomic hydrogen.
Yes. Our flexible R&D bases in Shanghai and Wuhan specialize in custom chemical adjustments. We tailor brightener and carrier concentrations to optimize deposition speed, thickness distribution, and surface brilliance for high-volume barrel plating lines.
