Arrow Cryogenics provides full-service chemical processing of metal parts and components. Our processing services can be used to improve corrosion and wear resistance, to prepare medical devices for implantation, to improve metal-to-rubber bonding, and for various other performance enhancements.
Our Chemical Processing Services
We offer a variety of chemical processing services for your part and component needs, some of which include:
- Aluminum Anodizing - Aluminum anodizing is a controlled electrochemical type of chemical processing that increases the thickness of the oxide layers that naturally exist on aluminum surfaces, improving corrosion resistance. Anodized coatings also provide better adhesion for paint primers and glues, and can be used for numerous aesthetic purposes as well.
- Hard Coat Aluminum Anodizing - Aluminum hard coat anodizing is like standard anodizing in that both are controlled electrochemical types of chemical processing. The key difference is that hard coat anodizing provides a surface that is more wear resistant and has a smoother and harder surface than standard anodizing. While aluminum naturally forms oxide on the surface over time, the aluminum oxide that is formed on the surface during the hardcoat anodizing process is more uniform, dense, and much harder than with natural oxidation.
- Chromate Conversion Coating - Chromate conversion coating is a chemical immersion type of chemical processing used by Arrow Cryogenics to passivate aluminum. This low-cost process is primarily used as a corrosion inhibitor and as a primer for paint, lacquer, or rubber bonding.
- Stainless Steel Passivation - Stainless steel passivation is a chemical process that makes stainless steel even less susceptible to corrosive environmental factors, such as air and water. While stainless steel is corrosion-resistant by nature, it is not entirely impervious to rusting. Iron embedded in the surface during part forming and machining can corrode and create rust spots on the stainless steel, called rouging. In stainless steel passivation, exogenous iron and/or iron compounds are removed from a stainless steel surface.
- Stainless Steel Electropolishing - Stainless steel electropolishing (or stainless steel polishing) is a “reverse plating” type of chemical processing. It uses a combination of rectified current and a blended chemical electrolyte bath to remove imperfections from the surface of metal parts and provide a surface that is clean and bright. Electropolishing is an effective replacement for more traditional mechanical finishing techniques.
All our chemical processing services are performed entirely in-house. The parameters of our chemical processing techniques are adjusted to meet our customers’ exact specifications. We also offer complete testing to verify quality after processing.
Additionally, we can provide cleaning services to remove contaminants from parts prior to chemical processing.
