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 →…
Anodizing is how metal gets that extra layer of strength—and sometimes, a better appearance too. There was this aluminum part I saw once—it looked ordinary, but somehow felt more solid, like it had a bit of extra protection. Later I…
