In the global supply chain for precision components, the journey from your CNC machine shop to the enduser can expose parts to various environmental threats. Corrosion, the gradual degradation of metals through chemical reactions, is a primary concern that can compromise dimensional accuracy, structural integrity, and aesthetic appeal, ultimately leading to product failure and customer dissatisfaction. For businesses sourcing CNC machined parts internationally, implementing robust corrosion protection is not just a technical step—it's a critical business strategy for ensuring quality, reducing returns, and building a reputation for reliability.

Passivation: Primarily for stainless steel, this chemical process removes free iron and enhances the natural chromium oxide layer, significantly boosting corrosion resistance without altering part dimensions.
Electroplating: Coatings like zinc (for steel), nickel, or chrome provide a sacrificial barrier. Zinc plating, especially with chromate conversion coatings (e.g., yellow, blue), offers excellent protection for ferrous parts.
Anodizing: An electrochemical process for aluminum that creates a hard, durable, and corrosionresistant oxide layer, which can also be dyed for color coding.
Powder Coating: A dry finishing process that applies a decorative and protective polymer layer, excellent for harsh environments and available in countless colors and textures.
AntiCorrosion Oils & VCI Packaging: For intransit or shortterm storage, specialized oils or Volatile Corrosion Inhibitor (VCI) films emit protective vapors that coat the parts.
