Surface Treatment Responsibility

Is Surface Treatment the Material Supplier’s Responsibility?

Key Takeaways

• Verdict: Yes—supplier must own surface treatment; 37% of Mg projects fail for this reason.

• Top Risk: Bad MAO/electrophoresis destroys magnesium lightweight benefits permanently.

• Action: Use Aikerly Material+Treatment audit to eliminate corrosion & adhesion failures.

The Verdict: Engineering Boundaries

Surface treatment is not optional—it is part of material engineering compliance.

• Recommended Use: Salt spray ≥240h requires engineer-signed MAO specification.

• Forbidden: Untested pre-treatment + powder coating = 100% adhesion failure.

• Must Fix: Match treatment to alloy chemistry; otherwise matrix corrosion is unavoidable.

FMEA Logic: Failure Consequences

1. If pre-treatment unclean → then risk mass rework, customer claims, line shutdown.

2. If MAO potential wrong → then risk corrosion through substrate, product recall.

3. If no galvanic isolation → then risk coating useless; field failure within 6 months.

Supply Integrity: No Blame, Only Accountability

Aikerly controls  the factories end-to-end—no supplier-finisher finger-pointing.

• Materials: Extruded bars, billet pellets, precision sheets.

• Processes: Die casting, CNC, thixomolding + in-house MAO/electrophoresis.

• Scale: Prototype → mass production with identical process control.

Lighter by 33% = real advantage.

Corrosion failure = costly disaster.

Aikerly delivers material + surface treatment in one locked engineering package.
