17 Special Grades H.C. Starck - the world s largest processor of molybdenum metal powder with over 40 years of experience, serves customers located around the globe. The Coldwater, Michigan plant manufactures a wide range of specially engineered molybdenum powders for variety of applications. H.C. Starck s molybdenum based thermal spray powders, BSP, PDMP, and SOMP, are spherically shaped particles produced by spray drying, atomization, and plasma densification. These powders have excellent flow characteristics and can be produced in coarse and fine grades. H.C. Starck can produce the thermal spray powders to customer or industry specifications, including automotive and aircraft specifications. Typical applications are wear resistant coatings for piston rings, synchronizing gears, plastic extrusion screws, gas turbine engine components, and valve stems. The thermal spray powders can be used to rebuild worn crankshafts and rollers and as a metallizing layer for ceramics. H.C. Starck s pure SOMP powder is used as filler material for weld wire or any other application requiring a flowable molybdenum powder. H.C. Starck s BSP powders are typically blends of SOMP and self-fluxing Ni alloys (typically following AMS 4775 chemistry), however, blends including NiCr (80/20) and / or Cr 3 C 2 can also be made. Each blend is made using a computer controlled loss-in-weight blending system which blends all ingredients into the final shipping container. Custom blend inquiries are welcome. Special Grades are produced at Coldwater, Michigan, U.S. H.C. Starck s SOMP powders are spray dried and sintered agglomerates of spherical particles. The spray drying imparts the spherical shape, while the sintering removes any binders and gives the powder strength to retain its shape during transfer in the thermal spray powder feeders. The SOMP powders are also available with elevated carbon contents as specified by the customer, as well as pure molybdenum carbide, in the coarse and fine grades. H.C. Starck s PDMP powders are plasma densified molybdenum powders in which the powder particles are 100% dense and spherical in shape. This powder is free flowing for applications requiring high coating densities.

22 Powder Production Methods Powder Production Methods There are several methods known to produce Thermal Spray Powders. H.C. Starck is using most of the following production methods to provide high quality powders. Powder Type Description Characteristics Examples Fused and crushed Fine materials will be melted using electric arc furnances. The melt will be cooled down and crushed. Two main processes are known: tap and block - Blocky - Irregular - Dense Cr 2 O 3 Al 2 O 3 Al 2 O 3 -TiO 2 TiO 2 ZrO 2 -Y 2 O 3 and crushed Raw materials (carbides, metals, oxides, etc.) will be blended and sintered in furnaces (under air, hydrogen or vacuum). The sinter cake will be crushed. - Blocky - Irregular - Relatively dense WC-Co Cr 3 C 2 -NiCr Cr 2 O 3 -based / sintered Suspension of fine powders, organic binder and liquid (f.e. water) will be atomized through an atomizer disk or through a nozzle into a chamber. Droplets (agglomerates of powder, binder and liquid) will be dryed and form solid particles. Typically the solid particles will be sintered afterwards. - Spherical - Porous - Homogeneous distribution of different materials WC-Co WC-Co-Cr Cr 3 C 2 -NiCr Mo Al 2 O 3 -TiO 2 ZrO 2 -Y 2 O 3 Gas atomized Molten metal or liquid alloys will be atomized with a high speed gas stream (high pressure) after a nozzle into a chamber. Used gases are Ar, N 2, He, air. - Spherical - Dense - High purity - Low O content MCrAlYs NiCr NiAl NiSF alloys Inconels Stellites Water atomized Molten metal or liquid alloys will be poured through a nozzle and atomized with a high pressure water stream into a chamber. - Irregular - Dense - Higher O content than gas atomized NiCr NiAl

23 Powder Type Description Characteristics Examples Dense coated Starting from an aquoeus metal salt solution in which particles to be coated will be distributed. The metal salt will be reduced with hydrogen by using an agitator autoclave under higher temperature and pressure. Typically used for Ni- and Co salts. - Blocky or irregular - Composite Cr 3 Cr 2 -Ni(Cr) Ni-Graphite WC-Ni Porous coated Coarser core material will be cladded on the surface with one or more finer powders using an organic binder. The materials and soluted organic binder will be put into a mixer, blended/milled and dryed. - Blocky or irregular Ni-Al NiCr-Al Ni-Mo-Al Spheroidized or sintered powders will be put through a plasma device. The particles will be partially melted and create a spherical shape with dense surfaces. - Spherical - Dense, porous and hollow ZrO 2 -Y 2 O 3 Cr 3 C 2 -NiCr WC-Co Blends All kinds of powders can be blended together using appropriate mixers. - Different morphologies - Segregation possible Mo-NiSF Al 2 O 3 -TiO 2 Cr 3 C 2 -NiCr Special Print H.C.
