Conversion coating
Phosphate coating services
Controlled phosphate treatment for suitable components, aligned with corrosion-control, lubrication or downstream finishing requirements.
Capability overview
Defined service.
Controlled outcomes.
Phosphate coating is a chemical conversion process that forms an adherent crystalline layer on a prepared metal surface. Depending on the specified chemistry and finish, it can support paint adhesion, temporary corrosion protection, lubricant retention or controlled running-in behaviour.
PICSA defines the complete treatment route around the component material and required outcome: incoming inspection, cleaning and preparation, phosphate chemistry, rinsing, drying, any specified post-treatment and final verification. The applicable phosphate type, coating weight, appearance and acceptance tests are confirmed for each scope.

What the service delivers
Designed around
the real requirement.
Every proposed service is defined against the asset, materials, operating context and agreed acceptance criteria.
Controlled conversion layer
Documented process checks
Inspection and batch handover
Typical applications
- Fabricated and machined steel components
- Components requiring a paint-preparation layer
- Fasteners, fittings and maintenance parts
- Surfaces requiring lubricant retention
- Workshop refurbishment and production batches
Scope considerations
- Base material and component condition
- Required phosphate chemistry and coating weight
- Dimensions, threads and critical tolerances
- Post-treatment, oiling or paint system
- Bath control, effluent and waste requirements
