Multispectral Zinc Sulfide (ZnS)

http://www.germaniumcrystals.com/zns-multispectral.htm

Multispectral Zinc Sulfide (ZnS). Cleartran TM, Irtran - 2, Clear ZnS. Cleartran TM, clear Multispectral and Irtran - 2 are all water-clear form of chemically vapor deposited (CVD) Zinc Sulfide. Modified to be Water free by a HIP process where the zinc hydrides are removed from the crystal lattice. Now the material has good transmission in the visible and infrared (0.4 to 14 microns). It is theoretically dense, chemically inert, non-hygroscopic and easy to machine. External windows for military systems.

Polishing HVOF WC-Co slab gate valve surfaces

http://www.valleydesign.com/HVOF-WC-Co.html

Polishing HVOF WC-Co slab gate valve surfaces. Finishing Tungsten Carbide Cobalt HVOF Surfaces. Tungsten Carbide Cobalt (WC-Co) coatings deposited by High Velocity Oxy-Fuel (HVOF) processes, produce very dense near zero porosity, and wear resistant surfaces. These characteristics make WC-Co coatings an ideal surface for high pressure slab gate valves to increase the strength and reliability for future savings in repair costs. As coated, the WC-Co surfaces are not flat, not smooth, nor parallel. Paralleli...
