Anodising is an electrochemical process that converts the surface of aluminium into a hard, durable aluminium oxide layer. The oxide layer grows into the metal surface — it is not a coating applied on top, but an integral transformation of the material itself. This makes it non-peeling and permanent. Anodising enhances hardness, corrosion resistance, and paint adhesion. Type II provides standard corrosion protection; Type III hard anodising delivers wear-resistant surfaces for engineering components to MIL-A-8625F.

Type II anodising produces a coating thickness of 1.8–25 µm, is suitable for decorative and general corrosion protection applications, and is typically used for consumer and architectural components. Type III hard anodising produces thicker layers of 25–150 µm at significantly higher hardness (250–500 HV), making it suitable for engineering components subject to abrasion, wear, and high contact stress. Type III is specified per MIL-A-8625F Type III and is preferred for hydraulic components, sliding assemblies, and aerospace structures.

Zinc phosphating is used primarily as a pre-treatment before painting or powder coating to improve adhesion and corrosion resistance under paint. It creates a crystalline conversion coating on steel that provides a mechanical key for primer systems and acts as a barrier to under-film corrosion creep. Phosphating is standard practice in automotive body preparation, appliance manufacturing, and architectural metal fabrication. It is also used as a base for lubrication on forming and drawing operations.

Passivation of stainless steel is a chemical treatment — typically using nitric or citric acid — that removes free iron, machining debris, and other surface contaminants embedded during fabrication. This allows the natural chromium oxide passive layer to reform fully, restoring the material's inherent corrosion resistance and preventing rust staining that would otherwise appear in service. Passivation is frequently specified per ASTM A967 or AMS 2700 for medical, food processing, and marine applications.

Surface Preparation surface preparation uses abrasive media — such as steel shot, steel grit, or aluminium oxide — projected at high velocity to remove mill scale, rust, old coatings, and surface contaminants. It simultaneously creates a surface profile (measured in microns Ra or Rz) that improves mechanical adhesion for subsequent coatings. The Sa2.5 near-white metal cleanliness standard is commonly specified for industrial coating applications. Fukar operates both automated and manual surface preparation for high-volume and complex-geometry components.
