The hard chrome process is widely used across industries for its wear resistance, durability and cost-effectiveness. At Australian Surface Technologies, we specialise in hard chrome plating to enhance the lifespan and performance of industrial components. Below, we take a look at the nuances of the hard chrome process and its many applications.

What is Hard Chrome Plating?

Hard chrome plating is a technique in which a layer of chromium is electroplated onto the surface of a metallic components. Unlike decorative chrome, which is primarily used for aesthetic purposes, hard chrome is all about functionality. This industrial-grade coating is engineered to withstand extreme wear, making it ideal for machinery parts, tools and components exposed to high levels of friction. The hard chrome process involves submerging the component in an chromic acid solution while applying an electric current. This causes chromium ions to bond with the surface of the metal, forming a dense, uniform and hard layer. The result is a protective barrier that enhances the performance and longevity of the part.

Key Benefits of the Hard Chrome Process

The hard chrome process offers several advantages that make it a preferred choice across various industries. Here’s a closer look at its benefits:

Wear & Abrasion Resistance

Hard chrome plating creates a tough, durable surface that can withstand constant wear and abrasion. This makes it a go-to solution for industries such as mining, manufacturing and automotive, where components are subjected to heavy use.

Sacrificial Wear Layer

A standout feature of hard chrome is its ability to act as a sacrificial wear layer. Over time, the chrome layer may degrade due to use, but the underlying base material will remain intact. This allows for quicker and more cost-effective repairs compared to replacing the entire part.

Enhanced Repairability & Lifespan

The ability to reapply hard chrome plating means that worn parts can often be repaired rather than replaced. This not only reduces downtime, but also extends the lifespan of components, making it a more sustainable and economical choice.

Food-Safe Applications

Hard chrome plating is considered food-safe, making it suitable for use in the food processing industry. Components such as rollers, blades and moulds can benefit from the process, as it provides a non-toxic, durable surface that complies with food safety standards.

Applications of Hard Chrome Plating

The versatility of the hard chrome process means it can be applied across a wide range of industries, including:
  • Automotive – Engine components, shock absorbers and hydraulic systems.
  • Manufacturing – Dies, moulds and cutting tools.
  • Mining – Drills, excavation equipment and wear plates.
  • Food Processing – Rollers and blades used in food production lines.
