Bonding

Process Materials, Inc. offers professional and diverse range of bonding services. Our bonding process ensures the thermal and electrical integrity of the interface between the system’s cooling assembly and the surface of the target. We can bond targets of any shape and material due to our proprietary solder metallization technology. Our process includes wetting, barrier interface, and adhesion.

Thermal Spraying

Surface modification technology is classified into thermal spraying and related technologies. Thermal spraying is a core competence of Process Materials, which is a technology that produces highly functional coatings onto the surface of various substrates. In this process, the metal, alloy or ceramic along with other materials are melted, then, the molten materials are sprayed on the substrate to form a coating layer.

Sintering

Compacted materials, especially compact ceramic parts, are able to achieve very high density through sintering. By precise control of the sintering temperature and atmosphere, these techniques provide the resulting targets with near theoretical density

Vacuum Metallurgy

The making, shaping, and treating of metals, alloys, and intermetallic and refractory metal compounds in a gaseous environment where the composition and partial pressures of the various components of the gas phase are carefully controlled. In many instances, this environment is a vacuum ranging from sub-atmospheric to ultrahigh vacuum (less than 760 torr or 101 kilopascals to 10-12 torr or 10-10 pascal). In other cases, reactive gases are deliberately added to the environment to produce the desired reactions, such as in reactive evaporation and sputtering processes and chemical vapor deposition. The processes in vacuum metallurgy involve liquid/solid, vapor/solid, and vapor/liquid/solid transitions. In addition, they include testing of metals in controlled environments.

There are three basic reasons for vacuum processing of metals: elimination of contamination from the processing environment, reduction of the level of impurities in the product, and deposition with a minimum of impurities. Contamination from the processing environment includes the container for the metal and the gas phase surrounding the metal. In the vacuum process, impurities, particularly oxygen, nitrogen, hydrogen, and carbon, are released from the molten metal and pumped away; and metals, alloys, and compounds are deposited with a minimum of entrained impurities. There are numerous and varied application areas for vacuum metallurgy including special areas of extractive metallurgy, melting processes, casting of shaped products, degassing of molten steel, heat treatment, surface treatment, vapor deposition, space processing, and joining processes.

Powder Metallurgy

Powder metallurgy is the process of blending fine powdered materials, pressing them into a desired shape, and then heating the compressed material in a controlled environment to bond the material. Process Materials produces high quality sputtering targets from carefully treated powders

Casting Metallurgy

Process Materials uses both vacuum and open air casting technology to produce non-ferrous metal-based targets, expecially low melting point metals. Target materials can be directly cast onto a backing plate or a backing tube and machined to the required specifications.
