Hard chrome plating is an electroplating process that involves applying a layer of chromium to a surface by submerging it in a chromic acid solution. Hard chrome plating can increase the durability, hardness, wear resistance and corrosion resistance of metal components for more effective use in machinery and equipment.

What is the hardness of hard chrome plating?

Industrial hard chrome can be deposited in a rather broad range of hardness depending upon plating bath parameters. Average hardness is in the range of 66 to 70 Rockwell C scale.

What is the difference between chrome and hard chrome?

What is the difference between chrome and hard chrome? The difference between hard chrome and decorative chrome is that hard chrome is used for wear resistance and decorative chrome is used for cosmetic purposes. For this reason, decorative chrome is usually much thinner than hard chrome.

What are the problems of hard chrome plating?

Why is chrome so hard?

Industrial Hard Chrome Plating

Chrome plating increases the hardness, durability, and corrosion resistance of a surface, while also creating a shiny and smooth surface that is easier to clean. For improved wear and corrosion resistance, it's tough to beat hard chrome plating.

Can chrome plating be done at home?

The chrome plating found on car trim and kitchen appliances can also be made at home. Using electrolysis, it's possible to bind chromium onto metals such as steel, brass, copper, aluminum and stainless steel, creating the shiny finish.

Why is chrome plating so expensive?

The chrome plating process is very expensive because of many factors. We use A LOT of electricity. ... Stripping the old coatings from your parts creates hazardous waste that is much more expensive to separate and treat than chrome plating rinse water. Regulatory compliance is very time consuming and therefore expensive.

What is the use of hard chrome plating?

Hard chrome plating can increase the durability, hardness, wear resistance and corrosion resistance of metal components for more effective use in machinery and equipment.

What are the pros and cons of chrome plating?

You can wash and polish it without worrying about scratching it up. Plus, as the layer of chrome provides a protective barrier for the underlying nickel, rust and corrosion should not be an issue. Cons: Chrome plating is expensive as hell.

Is chrome plating bad for you?

The problem with traditional chrome plating

Chromium contains Hexavalent chromium, which is a known carcinogen. The plating process uses lead, which can be absorbed through the skin and can cause liver, organ and brain damage. Cyanide is very toxic. It is used in the chrome-plating process and can be deadly to humans.

Is chrome harder than steel?

Stainless steel is more durable than chrome. It's corrosion-resistant, scratch-resistant, and tarnish resistant. ... Chrome is often chosen for decorating because it is brighter and shinier than stainless steel. However, because of the polished surface, it can also scratch easily and show fingerprints and dirt easily.

Are there different types of chrome plating?

There are two basic types of chrome plating: hard chrome plating and thin dense chrome plating. Hard chrome plating leaves a layer of chrome from 0.0008 to 0.0050 in. (from 0.020 to 0.127 mm) thick on the surface of the metal.

Can chrome plating chip?

Traditional chrome plating processes use thin layers of chromium to build up to a glossy chrome finish. ... Also, small errors in cleaning and preparing the substrate material can cause the chrome plating to chip and flake off sooner than expected. Most of these issues are preventable with hard chrome plating.

How do you test the hardness of chrome plating?

I suggest a Knoop microhardness tester, as it can measure thinner coatings than Vickers testers. Instruments with switchable Knoop and Vickers indenters are available if you also wish to measure hardened steel. The measurement method is given in ASTM E384 [affil.
