Metal Finishing FAQs
What is electroless nickel plating?
Electroless nickel plating is a chemical deposition process used to apply a nickel-phosphorus coating without electrical current. It is often selected for wear resistance, corrosion resistance, uniform coverage, and dimensional control.
What is the difference between alkaline zinc and chloride zinc?
Alkaline zinc and chloride zinc are two common zinc plating systems. Selection depends on substrate, part geometry, performance goals, bath behavior, appearance requirements, and the operating needs of the finishing line.
What chemicals are used for anodizing?
Anodizing operations may use cleaners, etchants, deoxidizers, acids, dyes, seals, bright dips, and supporting process chemistries depending on the aluminum alloy, finish requirement, and process specification.
What are chromates and passivates?
Chromates and passivates are post-treatment conversion coatings used after plating to improve corrosion resistance, surface performance, and finished-part appearance.
How do I improve corrosion resistance after plating?
Corrosion resistance can often be improved through the right plating chemistry, bath control, passivate or chromate selection, sealing, rinsing, drying, and process consistency across the finishing line.
Does Ronatec provide plating equipment and tanks?
Yes. Ronatec supports plating operations with tanks, process lines, electroless nickel equipment, filters, ventilation, chemical feeders, chillers, heaters, boilers, and related equipment support.
Does Ronatec provide wastewater treatment support?
Yes. Ronatec supports finishing operations with wastewater treatment chemistries, polymers, flocculants, precipitation agents, and related process guidance.
