Renishaw's inVia used for quality control analysis at New Plasma Technologies

4th September 2015

New Plasma Technologies (NPT), based in Moscow, Russia, uses a Renishaw inVia confocal Raman microscope for investigating the structure and chemical properties of materials, non-destructively.

NPT was founded in 2011 as a nanotechnology project for metallurgical applications, and provides high quality solid nanostructured coatings for cutting and forming tools. One of these technologies is a self-lubricating, wear resistant, diamond-like carbon (DLC) coating for metals, alloys, polymers and composite materials. This technology improves the materials' properties, giving them characteristics such as; high hardness (comparable with hardness of natural diamond), ecological cleanliness, low friction coefficient, biocompatibility and wear resistance. These features make DLC-coatings an important element for the manufacturing and application of products in many fields, including metalworking, mechanical engineering, space processing, defence, dental and medicine.

NPT uses its inVia confocal Raman microscope to control the quality of the coatings and help improve processing methods. The inVia's high spatial resolution makes it an ideal instrument for the analysis of DLC; its benefits include: little or no sample preparation; it is safe and efficient to operate; it is easy to use; it enables the rapid collection of high quality data without damaging the sample; and it acquires repeatable, reliable data.

One of NPT's DLC-coating quality control operations involves finding the ratio of sp2 (graphite-like) to sp3 (diamond-like) bonds, which determines the different properties and characteristics of the material (friction coefficient, adhesion, hardness). In the two years that NPT has had its inVia confocal Raman microscope, it has proven to be an indispensable instrument. In addition, Renishaw's Moscow-based Raman specialists have provided methodological and technical support, when required. Their ability to provide rapid solutions for any questions arising has substantially increased productivity.

In addition to the immediate improvement in DLC-coating quality, the inVia has enabled NPT to expand the scope of its research. Cooperation with research institutes and laboratories in Moscow, Novosibirsk, Belgorod and Kazan stimulated the interest for research not only in the field of DLC-coatings, but also for other materials. The inVia confocal Raman microscope is ideal for this because of its power and flexibility. It can be used to study and analyse a broad range of materials, including—but not limited to—polymers, coating compositions, paintwork materials, lacquer coatings, carbon-based composite materials, fibers, ceramics, minerals, semi conductive materials and nanomaterials.

The inVia Raman microscope has been used to great success by NPT and paves the way for more widespread applications of Raman spectroscopy for material quality control in Russia. For further information about Renishaw's Raman spectroscopy systems, visit
