Manganese Phosphating – Protective Surface Treatment for Steel Components

Manganese phosphating is a proven surface treatment process used to improve corrosion resistance, enhance oil retention, and provide a durable base layer for wear-prone components. It is widely used on industrial and downhole tool components to improve surface performance in harsh operational environments.

Scope of Service

• Manganese phosphate coating for steel components

• Surface preparation prior to phosphating

• Final sealing/oiling as required

• Coating for new parts and refurbished components

Benefits of Manganese Phosphating

• Improved corrosion resistance

• Better lubrication retention on metal surfaces

• Enhanced wear resistance in contacting areas

• Uniform matte finish suitable for industrial applications

Service Workflow

1. Degreasing and surface cleaning

2. Rust/scale removal and surface activation

3. Controlled manganese phosphating process

4. Rinsing and post-treatment sealing/oiling

5. Drying and final quality inspection

Quality & Inspection

• Visual inspection for coating uniformity

• Surface preparation verification

• Finish and consistency checks

FAQs

Q1: Is manganese phosphating suitable for downhole tools? A: Yes, it is commonly used for components requiring corrosion protection and improved surface durability.

Q2: Can phosphating be done on refurbished parts? A: Yes, phosphating is effective for both new and refurbished components after proper surface preparation.

Q3: Does phosphating replace paint? A: Phosphating is a protective conversion coating. Paint may still be used depending on application requirements.
