Surface Finishing Guides

Engineer's guide to aluminum coatings — anodizing vs powder coating vs plating comparison on corrosion, wear, cost, thickness, and alloy compatibility for OEM parts.

Engineer's guide to vacuum metalizing — process steps, coating thickness, cost comparison with electroplating and PVD, material selection, and application decision framework.

Engineer's guide to brass powder coat — pretreatment, adhesion testing, cost comparison with plating, and DFM tips for reliable finishing on non-ferrous parts.

Engineer's guide to polished vs brushed stainless steel — Ra values, No.4 and No.8 finishes, corrosion performance, and cost comparison for OEM applications.

Case hardening explained: process, types (carburizing, nitriding, induction), case depth, HRC values, cost, and how to choose the right method.

Engineer's guide to electroplating aluminum — zincate process, adhesion control, plating vs anodizing, thickness and cost trade-offs for OEM parts.

Heat treatment alters metal properties through controlled heating and cooling. Learn about annealing, quenching, tempering, carburizing, temperature ranges, and when to specify each process.

Complete guide to black anodizing — covering the process, Type II vs Type III, thickness impact on tolerances, alloy compatibility, cost factors, common defects, MIL-A-8625 standards, and industrial applications for CNC aluminum parts.

Complete guide to the screen printing process — covering step-by-step workflow, critical parameters (mesh, ink, curing), material compatibility for metal and plastic, cost analysis vs digital and laser, and industrial applications.

Complete guide to glass bead blasting — covering process mechanics, bead size and pressure parameters, Ra 1.6–3.2 µm finish data, material-specific settings for aluminum, stainless and titanium, and CNC finishing workflow integration.

Pick up any professional-grade drill bit or end mill and there's a good chance it has that characteristic gold color — that's titanium nitride coating, and it's not decorative.

Aluminum polishing is often mistaken for a purely aesthetic step, but in engineering practice it is a functional surface-finishing process.

A mirror finish on metal parts is not just for looks; it is also a functional surface specification that affects how well the part works and how easy it is to make.

Stainless steel is naturally resistant to corrosion, but it doesn't always meet the standards for wear resistance, surface hardness, friction control, or electrical performance.

To understand how brass oxidizes, you need to look at more than just the color change on the surface. You also need to look at the alloy's composition and how it behaves in an electrochemical way.
