Metal finishing started as a set of quick fixes on the shop floor. When parts left the lathe they might look fine, but after handling and storage small issues showed up—pinprick stains, slight discoloration, little rough spots. Shops didn’t wait for…
Metal Surface Coating In the metal industry, we often say that the surface decides the lifetime of the part. That’s not an exaggeration. Most metal failures start on the surface — corrosion, friction, heat damage — they all begin there.…
The core function of a pulse power rectifier is to convert alternating current (AC) into controllable pulsed direct current (DC). Its output is not continuous, smooth DC, but rather a pulse waveform with a specific frequency, duty cycle, and amplitude.…
Zinc plating is one of the simplest and most effective ways to stop metal from rusting. Basically, we coat the metal part with a layer of zinc — this zinc acts like a shield, corroding first to protect the metal underneath.…
Nickel plating for industrial parts begins with degreasing and light acid etching to ensure a clean surface. A copper underlayer, typically 5–10 μm, is applied to enhance adhesion. Electrolytic plating deposits nickel to the required thickness, usually 20–40 μm for machinery parts.…
If you’re looking to purchase a 50A ±12 V pulse rectifier for electroplating, here are some solid options and guidance on how to proceed: Liyuan Haina Rectifier Co., Ltd. offers the PNPF-50A/±12V Pulse Plating Rectifier, designed with air cooling, RS-485…
Hard anodizing pushes aluminum to its performance peak through a deep transformation of the surface itself. Components are immersed in a sulfuric acid electrolyte chilled to near-freezing, where controlled electrical currents trigger a reaction that converts the outer layer of aluminum…
You know aluminum? It’s a great metal, but to make it last longer and look better, there’s a trick called anodizing. Basically, you dunk aluminum parts into an acid bath and run electricity through it. This makes a thin, tough…
Mostly to keep the metal from going dark. Brass, copper—those change fast once exposed. So we add a thin layer on top. Could be gold, rhodium, depends. That layer blocks air, moisture, makes the surface hold up better. And for…
Anodizing gives aluminum a tougher, more corrosion-resistant surface using an electrochemical method. Anodizing Process： Aluminum workpiece → Mechanical polishing → Degreasing → Water rinse → Neutralization → Water rinse → Chemical or electrochemical polishing → Water rinse → Anodizing →…
