ADVANTAGES OF PVD COATING

PVD Coating has gained popularity over time due to its eco-friendly and durability features.  It is quite a preferred form of plating in numerous fields like aviation, aerospace and even the gaming industry. Let’s take you back a couple of decades ago to know how it all started?

With the development of electricity, concepts of magnetism, plating and the understanding of gaseous chemical reactions began. Physical vapor deposition, which is commonly known as PVD was discovered in 1852 by Robert grove who used the tip of the wire to coat a polished silver surface. The famous Thomas Edison made its application in his light bulb.

Over the years now the famous method of sputtering has gone through technical evolution leading to modern day PVD Coating process.

Advantages of Coating Include:

  • An Eco-friendly method with no use of chemicals. Other processes use chemicals and further require extensive cleanups.

  • Usage on inorganic material

  • Uniform and conformal coating – will not alter critical dimensional tolerances of components and parts
  • Corrosion resistant and chemically stable
  • Not affected by most acids and alkalis
  • Smoother workpiece surface finish – better chip evacuation on cutting tools and better mold release are just some examples
  • Lower maintenance cost –the significant increase in tool life relates to fewer tool changes and less machine down time
  • Reduces friction (increased lubricity)
  • Increased quality of the machined parts
  • Increased performance
