Processes Overview

Coating and Finishing Processes Built for Critical Parts.

Compare Entech's core finishing services by function, fit, and application — so you can move quickly from requirement to quote on the path that matches your part.

Each Process Solves a Different Problem

Pick the process that fits the part.

Some processes are designed for uniform coverage on complex geometries. Others are chosen for ductility, controlled thickness, corrosion resistance, or substrate preparation. If you already know your process, jump straight to it. If not, this page is the starting point.

Snapshot

Four processes at a glance.

A high-level comparison of function, best fit, typical substrates, and outcome — useful when you're triaging a part across multiple finishing options.

Process
Function
Best Fit
Typical Substrates
Outcome
Deposits a Ni-P alloy chemically — uniform coverage independent of current density.
Complex geometries, internal features, recesses.
Steel, stainless, aluminum, copper, brass.
Even thickness · corrosion resistance · wear life.
DC-driven nickel deposition — ductile, low-stress, controllable thickness.
Targeted build, repair, machinable deposits.
Conductive substrates · steel, aerospace alloys.
Ductility · controlled build · spec compliance.
Removes free iron and restores the corrosion-resistant chromium oxide layer.
Stainless parts post-machining or post-cleaning.
300- and 400-series stainless steel.
Cleaner surface · improved corrosion resistance.
Removes contaminants and conditions the substrate for downstream finishing.
Pre-plating prep, oxide and scale removal.
Most metallic substrates.
Predictable adhesion · consistent finish quality.
How We Help You Choose

Five things we look at first.

If you're still deciding, we evaluate a part across these five dimensions before recommending a process — so the part isn't forced into the wrong path.

01 Geometry
Internal features, recesses, edges, and complex contours often push the call toward electroless. Targeted-zone build favours electrolytic.
02 Material
Steel, stainless, aluminum, copper, brass, Invar, Inconel — each substrate brings its own preparation and compatibility considerations.
03 Performance
Corrosion resistance, wear life, ductility, surface cleanliness — the performance goal often points to one process over another.
04 Specification
ASTM, AMS, MIL, QQ, or customer-specific requirements may already specify the deposit, thickness, or process — when they do, we go directly to that path.
05 Downstream
Machining, assembly, mating tolerances, and inspection plans after finishing all influence which process protects the part best.
Backed By

Every process runs under AS9100D, ISO 9001 & NADCAP.
