How to Check PVD Coating Quality: A Guide from Vivid PVD Coating
When it comes to the application of Physical Vapor Deposition (PVD) coatings, quality is a top priority. At Vivid PVD Coating, they are dedicated to delivering the most accurate and reliable coatings. They understand the significance of every layer deposit and the importance of ensuring the final coatings are of the best possible quality. To guarantee this, they conduct several crucial tests. Here’s how you can check the quality of PVD coatings:
PVD Coating Quality
Coating Thickness Measurement
Among the important parameters that concern the quality of PVD coating one has to mention the thickness of the deposited layer. Vivid PVD Coating uses a color tester to help with coating thickness assessment on test plates and tools. In this process, a small cavity is formed in the coating, and the diameter of this cavity is noted. The exact thickness of the region is subsequently determined to be consistent with the requirements for coating thickness. Uniformity in the thickness of the coatings ensures that the coated products deliver their best performance levels and that durability is ensured.
Adhesion Evaluation
Adhesion assessment is another major quality control test. Vivid PVD Coating also uses techniques such as the Rockwell or scratch tester to determine how effectively the coating has bonded with the substrate material. The Rockwell test involves the use of an anvil to place a diamond indenter against the coated surface and investigate the mark made. For a coating to have minimal deformation, it should adhere properly. The scratch test, on the other hand, involves a gradual increase in the applied pressure on the coating until it peels off.

Visual and Microscopic Inspection
In addition to these tests, visual and microscopic inspections are carried out by Vivid PVD Coating. There is a very keen step of inspecting the coated area for signs of any possible defects, including pinholes, cracks, or uneven coating. Thanks to more sophisticated microscopes, they are able to observe defects that are not visible to the human eye and always produce only high-quality products.
Conclusion:
By applying these rigorous testing techniques, Vivid PVD Coating ensures the superior quality of their PVD coatings. They leave no aspect unchecked, from thickness measurement to adhesion assessment and microscopic scrutiny. Their commitment to accuracy and excellence is unwavering. Choosing Vivid PVD Coating means you can rely on unparalleled precision and quality to achieve your desired outcome.
