New CD Coating Enables Manufacturers To Operate At Higher Voltages
A Charge Dissipative (CD) coating capability for ceramic
parts – launched by the Technical Ceramics business of Morgan Advanced
Materials at RSNA 2017 in Chicago – is supporting the development of
increasingly compact medical equipment.
One of the biggest drivers in the medical diagnostic imaging
equipment market is the need for smaller and lighter weight x-ray sources. For
imaging systems such as Computed Tomography (CT) scanners, technology is
shifting towards smaller size and reduced rotating mass. Likewise, the growing
popularity of mobile X-ray machines places the emphasis on convenience and
While the desire among manufacturers is to reduce system
size, there is also the demand for improved resolution and imaging performance,
which can be achieved by using higher operating voltages. This is where
Morgan’s CD coating provides a major benefit. Coating of the ceramic parts
facilitates optimum performance at higher voltages. Morgan Advanced Materials
is making significant advancements with its new capability to coat components
with a tailor-made Specific Surface Resistance (SSR).
For manufacturers’ development projects, Morgan will supply
multiple coated samples, each with varying SSR. Development of a measurement
system for SSR on complex ceramic shapes enables better consistency and
repeatability that is critical for X-ray source manufacturers. Significant
investment in automation and kilns at its German manufacturing facility gives
Morgan the flexibility to offer reduced prototyping times to customers. Its
latest range of coatings use a blend of titanium and chromium oxides that
provide semi-conducting layers and suppress the emission of secondary
electrons, to meet the future technical requirements of X-ray sources.
Joerg-Uwe Wichert, Manager New Business at Morgan’s
Technical Ceramics business explains: “Our new capability is designed to
support manufacturers to deliver increasingly compact, efficient and patient
friendly medical systems. With smaller parts, there is a corresponding need to
adjust the blend of CD coatings to maintain the best SSR and charge dissipation
performance. That’s why we’ve invested in materials and capacity to ensure that
customers will always get the fast track for new products. "
Morgan’s latest CD coatings will be launched at radiology
exhibition RSNA 2017, held 26-30 November in Chicago, USA. Join the team on
Booth 2765C for a first glimpse of the work Morgan is doing with CD coatings.
