With the JCM-6000, sample preparation is minimal compared to that required for more traditional SEMs or even optical microscopes. One characteristic of the benchtop SEM from Nikon Metrology is that electrically resistant materials can be analysed without applying a conductive coating to the surface, which is not the case with most SEMs on the market. Therefore non-destructive tests on ceramic components can be performed quickly.
Moreover, the depth of field on an SEM is much greater than on most optical instruments, facilitating analysis on the surface and also on raised features or cavities of samples, allowing Morgan to gather a greater amount of information.
Development of friction materials for pumps Morgan's Stourport facility is also a major supplier of high- precision components which are supplied to market-leading pump manufacturers. A new friction material has recently been developed for hard-wearing pump seal applications in demanding industrial and petrochemical processing environments. The material has a composite structure, which enabled Morgan's materials scientists to tailor its friction performance for use in harsh field conditions.
The JCM-6000, with its energy dispersive spectrometry (EDS) capability, played a key role in the development of the material. It enabled the company to tailor its elemental composition and composite structure, using both the SEM's back scattered electron detector and elemental mapping feature.
