Adhesion and hardness of galvanic layers by scratch test and nanoindentation
Galvanic layers are crucial for protecting surfaces from corrosion and increasing durability. Accurate assessments using scratch tests and nanoindentation offer valuable insights into the adhesion and hardness of these coatings, helping in the enhancement of their performance.
Galvanic layers, also known as electroplated coatings, are metallic layers applied to substrates via electrochemical processes, offering protection to components regularly exposed to harsh environments and mechanical stresses. Various metals can be used depending on the application; for example, a zinc coating on steel, as produced by Radmot, effectively protects against corrosion. Nickel coatings from Kanigen enhance both durability, including corrosion resistance, and the aesthetic appeal of complex or irregularly shaped parts.
Industries that heavily rely on galvanic layers include automotive, electronics, watch manufacturing but also the production of faucets and bathroom fixtures. In the watch industry, these coatings improve the appearance and durability of watch cases and arm bands, ensuring they remain attractive and functional over time. In all these applications excellent durability and adhesion of the protective galvanic layer is required. Premature delamination or layer removal will lead to loss of its protecting function. Similarly, low hardness of the layer is often related to non-sufficient wear resistance and often indicates problems in the deposition process. It is therefore crucial to measure the adhesion and hardness of the galvanic layers to ensure their best quality.
