Phosphating Melbourne — Precision Anti-Corrosion Treatment

Blastoff Surface Cleaning & Protective Coatings is a trusted provider of phosphate coating services in Melbourne, offering reliable anti-corrosion treatments for cast iron, steel, and other substrates. With over 30 years of industry experience, our workshop applies phosphating solutions that chemically bond with the surface to improve corrosion resistance, paint adhesion, and overall durability.

Phosphating is typically applied after Abrasive Blasting or Hydro Blasting, when the surface has been stripped and cleaned. The phosphate solution, heated to near-boiling temperature, reacts with the metal to create a crystalline layer. This treatment reduces the risk of rust and provides an ideal base for Industrial Painting or Epoxy Coatings.

Why Phosphating?

    • Creates a protective anti-corrosion barrier.
    • Provides an excellent substrate for paints and coatings.
    • Improves wear resistance and lubricity for moving parts.
    • Reduces flash rust during the coating process.
    • Suitable for industrial, automotive, and restoration applications.

    Common Phosphating Applications:

    • Cast iron components.
    • Automotive parts (engine blocks, brake components).
    • Fabricated steel structures.
    • Tools, fasteners, and small mechanical parts.
    • Heritage ironwork requiring rust prevention.

How It Works

Surface Preparation

Surfaces are cleaned and treated with Abrasive Blasting to remove coatings, rust, and contaminants.

Phosphate Bath Application

Parts are treated with a heated phosphate solution that chemically bonds with the surface.

Rinsing & Drying

Excess solution is rinsed away, leaving behind a durable phosphate layer.

Protective Coatings (Optional)

Surfaces can be sealed with Industrial Painting or Epoxy Coating for enhanced durability.

Inspection & QA

Final checks confirm coating uniformity, adhesion readiness, and anti-corrosion performance.
