Bringing It In House: Surface Treatment and Magnesium Phosphate Coating at Scan Engineering

As our machining capabilities grow, so do the expectations of our clients — especially in the oilfield, defense, and aerospace sectors where surface protection is critical. That is why we have taken the next step: bringing surface treatment operations and magnesium phosphate coating fully in house.This new addition gives us tighter control over corrosion resistance, wear performance, and delivery timelines — all while keeping quality in our hands, not outsourced.

What is Magnesium Phosphate Coating

Magnesium phosphate coating is a type of conversion coating applied to ferrous metals. It provides

• Excellent wear resistance

• Solid corrosion protection

• A reliable base layer for oil retention or paint

• Better performance in high friction or threaded parts

It is widely used in defense, oilfield, and mechanical assemblies, especially where durability and dimensional accuracy matter.

Why We Are Doing This In House

Previously, we relied on external vendors but this created delays, quality inconsistencies, and limited flexibility for urgent jobs. Now, with full in house control, we can

• Reduce turnaround time

• Ensure consistent quality

• Customize coating specs per job

• Integrate it tightly with machining and inspection flow

Parts We Currently Support for In House Coating

• Oilfield fasteners and threaded adapters

• Aerospace mounting brackets

• Bearing housings and shaft collars

• Tooling fixtures and clamping plates

• Structural pins, sleeves, and couplings

Quality That Matches International Standards

We have aligned the setup with

• MIL DTL 16232 (US military phosphate coating standard)

• ISO 9717 (phosphate conversion coating process)

• Customer specific callouts and salt spray test validation

In house surface treatment also helps us prepare for future AS9100 and API monogram audits, where integrated processes and traceability are key.

At Scan Engineering, we do not just build parts. We build complete, ready to perform components. Bringing surface treatment in house is one more step toward total process control and total confidence.
