H.C. Starck Solutions has emerged as one of the leading suppliers of advanced shielding parts for radiation and heat management, and superconductivity applications.

Shielding Parts for High-Technology Applications

The density of a material is an essential factor in its radiation absorption properties. Heavier metals like tantalum (with a density of ~16.6 g/cm3) and tungsten (~19.3g/cm3) are more effective at absorbing radiation across the full spectrum – including X-rays and infrared (IR) waves – than conventional structural materials. Yet, the inherent properties of these metals make them very difficult to fabricate into finished components with the tight tolerances required of high-technology applications.

H.C. Starck Solutions has over 20 years’ experience in the field of manufacturing intricate components using high-performance refractory metals for the medical sector. Specializing in the generation of fabricated shielding parts for medical and industrial applications, H.C. Starck Solutions offers tailored radiation management solutions comprised of some of the heaviest metals on earth. These capabilities are buoyed by expertise in the fields of CNC grinding, milling, and lathe turning for numerous refractory material types.

With unmatched experience in the fabrication of high-technology parts using refractory metals and alloys, like tungsten and molybdenum (Mo), H.C. Starck Solutions can reliably produce and supply collimators for radiation management in CT scanners and radiotherapy applications.

Collimators for Radiation Management

Collimators manage radiation by either focusing an X-ray source into a manageable, parallel beam of rays that is directed onto an area of interest, or by absorbing scattered rays before they enter photodetectors. Lead (Pb) and depleted uranium have been used in the past, but tungsten has emerged as the ideal replacement for multi-leaf collimators in radiation therapy beam focusing and detector plates in CT scanners for a number of reasons.

Tungsten is a remarkable metal with a notably high density (~19.3g/cm3), which makes it suited for radiation shielding in complex medical apparatuses. It is widely used in the medical diagnostics market to fabricate collimators for both beam focusing and CT scanner assemblies. The outstanding mechanical properties complicate its workability, however, and the fabrication of multi-leaf tungsten collimators requires significant experience in precision machining and tolerancing of refractory metal parts.  

H.C. Starck Solutions fabricated products and services are routinely supplied as robust solutions for intricate challenges in the medical technology sector. With high capability inspection equipment and unmatched expertise in working dense metals like tungsten, H.C. Starck Solutions has emerged as one of the leading suppliers of collimators for CT scanning and radiotherapy applications. All fabricated components can be rapidly and reliably finished, with a contact-free quality assurance and control process guaranteeing components are form fit with a resolution of approximately 0.1 – 1 micrometer (μm).

Within H.C. Starck Solutions electro-plating processes are finely tuned to ensure consistent and high quality results. Adhesion and integrity are vital to the reliability of semiconductor devices, and all coatings are diffusion bonded to the molybdenum by sintering under selected time – temperature cycles. The inter diffusion of substrate and coating then guarantee the adhesion of the surface layer, interracial and intergranular oxides are dispersed, the surface layer is annealed and consolidated and the exposed surface is cleaned and degassed. These are all ideal preparations for solder-wetting, electrical contact or corrosion protection. For soldering and alloying applications, excellent wetting and adhesion can be obtained with any hard or soft solder, eliminating the need for expensive and capricious special solders which are highly sensitive to conditions and can require unnecessarily high temperatures.

Pressure contact devices benefit from the use of discs coated to optimise tribiological and electrical contact properties, and modern techniques permit 100% adhesion of these coatings whilst providing less than one micron flatness deviation.

Coatings can be supplied on one, both, or all sides of the product and our technical staff are always available to advise the best coating for your application.

Among other applications, H.C. Starck Solutions generates advanced bearing parts for cutting-edge medical technology applications.

Bearing Parts for Radiation Management

X-ray imaging is a critical tool that intersects numerous fields of medical and healthcare services, from dentistry to veterinary medicine. Every medical system that uses X-rays to produce images of bone structures is built around a core device: The X-ray tube. This is used to convert an electrical input into a controllable source of X-radiation which occupies the electromagnetic spectrum from approximately 0.01 – 10 nanometers (nm).

Only a limited amount of energy supplied is successfully converted into X-rays, while the rest is converted into heat. To counteract potential thermal degradation of integral components in the X-ray tube, a rotating anode is used to dissipate process heat. This requires advanced bearings and bearing parts to continuously rotate an anode in the high vacuum (HV) of an X-ray tube, with 360° of motion.

H.C. Starck Solutions has over 20 years’ experience in the development of spiral grooved bearings using refractory metals and alloys. With exceptional wear-resistant and thermal conductivity properties, molybdenum and its alloys have successfully been applied for complex bearing assemblies in X-ray tubes. H.C. Starck Solutions unmatched experienced in cutting, tuning, and finishing fabricated refractory components also guarantees uniform tribological properties for limited friction and mechanical resistance. H.C. Starck Solutions bearings and bearing parts are subsequently well-equipped for long-service in X-ray imaging assemblies, with outstanding resistance to process G-forces, noise, temperature, rotational speeds, and vibration.
