Quality Assurance
A finished component is only as good as the verification behind it. Powernox's quality-control capabilities include coating thickness measurement, hardness testing, and surface roughness testing, with QA documentation supplied where applicable.
What It Does
Verification, not just visual inspection.
A hardened or coated surface can look correct and still miss the job's specification. Measurement instruments — thickness gauges, hardness testers, and surface roughness testers — confirm that a finished component actually meets the hardness, thickness, and finish it was ordered against, before it ships.
Quality verification supports all three core services and is reviewed according to each job's specification, not applied as a generic checklist.
Verification Sequence — Representative
Coating Thickness Measurement
Thickness — VerifiedConfirms the plated or coated layer meets the required thickness for the job.
Hardness Testing
Hardness — VerifiedVerifies surface hardness against the required Vickers (HV) or Rockwell (HRC) specification.
Surface Roughness Testing
Finish — VerifiedChecks the finished surface against the required roughness or finish specification.
QA Documentation
Record — LoggedSupplied with jobs where applicable, to support verification and traceability.
Representative sequence, not a fixed checklist or job record — the checks actually performed, and their results, depend on each component's specification.
How It Works
From specification to verified delivery.
Specification Review
The job's required hardness, thickness, or finish is confirmed before work begins.
Measurement & Testing
Coating thickness, hardness, and surface roughness are measured as relevant to the service.
Documentation
QA documentation is supplied with the job where applicable.
Delivery
Verified components are released only once they meet the job's specification.
Common Questions
Before you send a drawing.
Depending on the service, Powernox verifies coating thickness, hardness, and surface roughness against the job requirement, with QA documentation supplied where applicable.
Yes. Share your requirements when submitting an enquiry, and Powernox will confirm what verification applies to your job.
Yes. Coating thickness, hardness, and surface roughness verification support hard chrome plating, PVD coating, and heat treatment jobs as applicable to each.
Yes. Alongside verifying its own plating and treatment work, Powernox also provides coating thickness measurement, hardness testing, and surface roughness testing as a standalone service where a component simply needs to be checked against its specification.
