Coatings

Here we share some of the processes and materials that are used for metal coatings that we interact with every day and their history in our domestic and commercial environments.
PVD coatings in the salon industry

PVD coatings in the salon industry

Millions of pairs of PVD coated scissors are produced every month, here's why. PVD coatings stand up to most endurance tests and are now performing well at the sharp end - that is as a coating on scissors used in hairdressing salons and barbers. Cutting to the quick; how are PVD coated shears better than simple stainless steel scissors? The coating applied to the scissors is a layer of TiN (Titanium Nitride) by using the PVD metal coating process. With this coating the scissors become considerably more robust. The measured hardness of the TiN layer is something in the order…
PVD, the fashion favourite

PVD, the fashion favourite

Looking at how PVD coating is used in the world of jewellery and fashion accessories. Why use PVD (Physical Vapour Deposition) coatings for watches and jewellery? First of all, the finish won’t wear off. It increases the life of bracelets, crowns and bezels and adds a unique professional appearance to timepieces and virtually wipes out the issue of reflective glare. As the deposition process is so flexible many industries have begun using this exciting technology. Tag Heuer Racer is a an Android smart phone from Swiss watch-maker Tag Heuer. How is PVD applied? PVD is applied in a similar method…
What is PVD coating?

What is PVD coating?

This apparently incredibly modern finishing process has its origins in the seventeenth century. Physical Vapour Deposition (PVD) is a technique used to deposit thin films of one atom (or one molecule) at a time onto various surfaces, often metal, to give them a hard durable coating. The source of the coating is physical that is a solid or liquid instead of chemical as in the alternative coating process of Chemical Vapour Deposition (CVD). PVD processes are carried out under vacuum conditions. The process involves four steps: These are Evaporation, Transportation, Reaction, Deposition. Evaporation - A target is bombarded by a…
PVD coating – a finish for all seasons

PVD coating – a finish for all seasons

PVD coated coloured stainless steel is used in the creation of sculpture, architecture, jewellery, phones and is used for interiors and exteriors. We look at this very versatile medium. PVD coating - a spectrum of colour options When it comes to stainless steel you’re not just restricted to simply silver. There are a rainbow of colour opportunities which can be achieved through the Physical Vapour Deposition (PVD) process. Jeff Koons Balloon Flower - Magenta The process of PVD coating During the process, first of all the stainless steel is cleaned to make sure that the coating will bond well. The…

How are PVD coatings used?

We roam around in the world of PVD coatings to see what, in our everyday world, it is used for. And of course, how is it actually done. High quality coatings achieved by Physical Vapour Deposition have wider uses than most people realise – on car engines, double glazed units, bath taps, drill bits, mobile phones, spectacles – the list is endless. The market is growing at 10 per cent per year and with annual sales in excess of £2 billion. PVD coating in the car industry In the car industry, it is a newer and much cleaner alternative to…
Antimicrobial Decorative finishes

Antimicrobial Decorative finishes

Can a decorative finish kill bacteria too? We look at some of the old and new technology that does exactly that. Can coatings add more to surfaces than durability and decoration? The answer is yes - not only can the surface of a countertop look more attractive or the handle on a fridge look like chrome – but coatings applied using the PVD process can help fight invisible germs. This is done by incorporating antimicrobial additives into the hard surface coating. Killing infection in hospitals and clinics Repeated testing reliably concludes that these coatings can be effective in helping to…
