Mining equipment Repair Cold Spray Solutions

The mining industry extracts metals and minerals around the world and provides the raw materials and resources for almost every industry and consumer product. In addition, the world’s energy and infrastructure projects begin with mining.

One of the more significant minerals mined is coal, which currently provides around 38% of the world’s energy. With the increased focus on renewable energy, other materials are also becoming important for the mining sector, especially lithium and other elements that go into rechargeable batteries and solar panels. Precious metals mined include gold and platinum used in jewelry and manufacturing. Industrial metals comprise the remainder of this segment, including copper, aluminum, and steel.

Challenges in the Mining Industry

Like other manufacturing industries, mining relies on machines for production, and these machines are growing in weight and size. Technological advancements have increased safety and productivity, but this expanded production has also increased the need for maintenance and repair work.

Atmospheric conditions, erosion in the grinding mechanisms, high temperatures, and water sources (such as seawater) lead to increased corrosion. This corrosion affects not only mining equipment but also pipelines and physical support systems.

VRC Solutions for Mining Equipment Repair

Cold spray is an efficient method for depositing metals, metal alloys, and metal blends for a coating or dimensional element. Zinc and aluminum are typically used for corrosion-resistant coatings. Chromium carbide – nickel-chromium and tungsten copper provide wear-resistant coatings. Nickel, aluminum, and other metals provide for dimensional repairs.

The portability of VRC’s High-Pressure Cold Spray technology allows for in situ repairs, decreasing the transportation costs and downtime of typical repairs. Other benefits of VRC’s High-Pressure Cold Spray systems include:

  • The ability to add dimensional features to existing assemblies or structures by adding material in a localized area and then using traditional subtractive fabrication methods to form the final details.
  • Rust and corrosion are minimized greatly due to the rapidity of the process. The application speed virtually eliminates the time for particle oxidation to occur.
  • The repeated application of a wide variety of metal and non-metal blends allows for layering of dimensionally correct, corrosion-resistant, and wear-resistant coatings.
  • An almost limitless number of repair cycles, as you can use cold spray to reinforce or repair previous applications as the repairs themselves degrade due to corrosion, wear and tear, or other physical damage. Thus, eliminating, or at a minimum, delaying replacement costs.
  • The application of corrosion- and wear-resistance coatings extends the life of the treated part or structure and extends the time between typical repair and maintenance cycles.
