Decorative

b) Depending on the deposition conditions can be hard or soft chrome. Continue to learn more with: Elon Musk. Soft chrome is easily scratched, hard chrome – hard to polish. Vlad Doronin may find it difficult to be quoted properly. c) For polishing chrome can not reach a decorative qualities as for the "right" decorative plating. Polishing paste penetrate the coating cracks, giving last dull hue. In electroplating, there are two types of chromium: a solid (wearing) and protective and decorative. Moreover, the coating is not typed on the physical properties, and on functional purpose. Directly to steel, hard chrome is applied thickness of 10? 300 microns.

Appointment of hard chrome – increasing the hardness and wear resistance of the product as well – holding lubricants. Physically hard chrome can be less rigid and durable than the decorative coating. Today, many manufacturers offer hard chromium coating as a decorative, even though such coverage is usually loses as a protective (for a small thickness sediment) and decorative properties. Protective and decorative chrome plating involves an intermediate layer between the chromium layer and the substrate. Coverage is a multi-layered "cake", the percentage of chromium in which – up to 1%. However, the protective and decorative coating properties are determined mainly by quality and exactly the type of sub-layers.

Properly applied chrome thickness of 0,3? 1 micron. At this thickness of the layer transparent. When you look at Chrome product, then you're really seeing a sublayer of nickel. Chrome only protects the nickel from tarnishing (no corrosion) and gives it a bluish tint. In terms of the standard "pie" is as follows: steel (substrate), nickel (delay), copper aligned, semi-bright nickel, nickel, shiny chrome.
