Plating

PLATING

Material processing for challenging applications often requires a novel solution. H.C. Starck Solutions highly qualified process engineers and developers have long been collaborating with customers to meet unique industry requirements with value-added resolutions. This has culminated in one of the core services on offer from H.C. Starck Solutions. Using high-purity molybdenum (Mo) as a base material, H.C. Starck Solutions routinely generates composite plates using a choice of electrodeposited metals, including:

  • Precious metals like gold (Au) and silver (Ag).
  • Transition metals like nickel (Ni), rhodium (Rh, and ruthenium (Ru).

H.C. Starck Solutions plating service exploits the exceptional thermodynamic properties of molybdenum, including its high strength and stiffness under refractory conditions. It is one of the highest performing substrate materials for plating in aerospace and defense, electronics, and industrial processing applications, benefitting from exceptional adherence with deposited metal coatings. H.C. Starck Solutions molybdenum plates can withstand extremely high temperatures without softening or expanding, enabling the functional coating to retain its desired characteristics throughout operating conditions.

The challenge of electroplating on molybdenum substrates is the material’s relatively high reactivity with other metals. This can result in the generation of undesirable oxides that inhibit adhesion between the substrate and the coating material. H.C. Starck Solutions has a wealth of experience in design and engineering with challenging refractories, including molybdenum and its alloys. These problems can subsequently be overcome with confidence, ensuring uniform functional coatings of high-performance molybdenum substrates for sectors as challenging as semiconductor and chemical processing.

Tungsten discs, washers and squares for power semiconductors

Tungsten is widely used as contact materials in silicon controlled rectifiers diodes, transistors and thyristors (GTO’S). Other than in specialist applications, molybdenum is now accepted as the first choice mounting material for power semiconductor devices due to its significantly lower cost and weight.

The fact that both materials have a similar coefficient of expansion to silicon combined with high thermal conductivity makes them an ideal choice, especially in large area power devices where considerable heat is generated. Further applications include the use of molybdenum and tungsten as heat sink bases in IC’S, LSI’S and hybrid circuits.

Vacuum Arc-Cast Molybdenum Mill Products

The VAC method of consolidation is unique to H.C. Starck Solutions. Materials made by this process is available exclusively from H.C. Starck Solutions and yields a homogeneous product which is very low in residual elements, provides better strength at elevated temperatures and exhibits excellent workability, weld-ability and good machining characteristics.

In the vacuum arc-casting process, 99.95% pure molybdenum powder, ultra-pure molybdenum powder or one of our molybdenum-base alloys is pressed, sintered, and melted (all under vacuum) to produce a casting weighing up to one ton. This arc-casting is then further worked by extrusion followed by forging or rolling.

Where highest purity, maximum toughness, and ductility at low temperatures are required, arc-cast molybdenum mill products are available in a special low-carbon grade. This material is 99.97% pure molybdenum and contains a maximum of .010% residual carbon, compared to the nominal .030% maximum carbon content of normal arc-cast molybdenum.

Workability and machinability are also superior with this special product.

H.C. Starck Solutions produces a wide range of molybdenum and molybdenum alloy mill products using two primary consolidation methods; vacuum arc-casting (AC) and powder metallurgy (PM). The availability of products from both of these established processes gives users many options in selecting a material to satisfy their specific application requirements. Mill products available from either process include forging billets, bar, rod, sheet, plate and foil.
