Optical Coatings

What Are Optical Coatings? Optical Coatings are typically viewed as a classification of Thin Films deposited onto an optical substrate for the purpose of modifying or altering the transmission, reflection absorption or polarization of light properties.  Thin film...

Corrosion Resistant Thin Films

What Are Corrosion Resistant Thin Films? Many industrial applications for base materials require Thin Film Coatings that can help parts to sustain high temperatures, corrosive environments or both.  In a previous BLOG we covered the need for high temperature...

Hard Coatings

What Are Hard Coatings? Hard coatings, in one form or another, have been around for a long time.  The need to preserve or protect the surface of materials is not new.  From the prehistoric period of the Stone Age to the advent of metal working, man has been trying to...

Cathodic Arc Deposition

What Are Cathodic Arc Depositions? In the past, we have discussed numerous forms of Physical Vapor Deposition (PVD) technologies including Sputtering (r.f. and DC), Resistance Evaporation, Electron Beam Evaporation, and Pulsed Sputter Deposition. In this article I...

Ion Beam Deposition

Another form of Physical Vapor Deposition (PVD) is referred to as Ion Beam Deposition or Ion Beam Sputtering (IBS). Unlike conventional magnetron sputtering, where ions are generated in plasma within a cathode assembly, Ion Beam Sputtering employs a target that is...

Electron Beam and Physical Vapor Deposition

In the last BLOG article I described the simplest form of resistance evaporation. That involved heating a resistance filament in a vacuum environment which in turn heats an evaporant material that is either melted or sublimated. The vapor created in the process is...

Thermal Evaporation

What Is Thermal Evaporation? Over the past few years we have provided a series of BLOG articles discussing various aspects of Physical Vapor Deposition (PVD) as they relate specifically to Sputter Deposition. However, sputtering is only one subset of PVD processing....

Sintering of Ceramic Sputtering Targets

A while back (January 2016) we discussed a brief but fundamental description of what the basic processes are associated with the production of elemental and metal alloy sputtering targets. At that time we promised to address the analogous process of how ceramic, or...
