Hard Chrome Plating for Aviation (& other Industries)
|
|
What is Hard Chrome Plating? |
Hard Chromium is an electroplating process by which a liquid chromic acid bath deposits a layer of chromium metal directly onto the part. It is often utilized in the most extreme working environments due to its ability in extending corrosion protection, significantly increase wear resistance and reduce friction for anti-seize applications. Chrome plating also has the capabilities to adhere to various different materials when performing the correct activation process, which makes it an ideal coating on several common and also unique base materials.
Its important to note there at two distinct forms of Hard Chrome Plating. Bright or Decorative chrome plating often seen in the automotive industry and custom performance. Secondly, Hard or Engineered chromium plating which can be found in the working industries around the world. |
|
How do we apply Hard Chrome Plating? |
Hard Chrome is plated in a traditional Chromium trioxide electroplating bath utilizing high current densities. Significant power and quite often long soak cycles are required to achieve higher deposits for restoration purposes. In most cases due to chromes inefficient and weak throwing power capabilities, complex jobs with unique shapes and geometry often require custom made anodes to place the current as close to the substrate to be plated as possible. This allows the plating bath to achieve a uniform deposit and increase efficiency during the plating cycle.
Unlike most of other plating options, chromes deposition rate is quite slow and thus requires plating cycles that extend many hours of plating time. The slow plating and lower temperatures required contribute to Chromes attributes such as extreme hardness values. |
|
What aviation components typically receive Hard Chrome Plating? |
The Aviation industry has a strong network of utilizing Hard Chrome Plating on countless and various overhauls and applications. These include but are not limited to, Dimensional restoration on both Outside and Internal working Diameters on parts that range from small Tachometer gears to major components such as Transmission cases and Propeller Turbine Supports. Areas subject to high wear and critical sections, Chromium is a common and beneficial choice among the aviation community. |
|
What are the major benefits to Hard Chrome Plating? |
One benefit which immediately stands out for Hard Chrome Plating is the increases hardness value the coating achieves. Typically in excess of 1000HV100 on the Vickers scale, Chrome adds a benefit that leaves little options as a potential replacement or alternative. Accompany that with increased wear, reduced friction and anti seize application, Chrome plating benefits extend well beyond the typical norm in electroplating. These reasons, along with numerous others are why Aviation and countless other industries rely on Hard Chrome plating for the most crucial repairs out there. |
