Surface texturing is more and more frequently used in modern machines to attain such aims as lubrication enhancement, heat flow intensification and micro-flow stimulation. The development of technologies using concentrated energy flux, e.g. laser technology, has contributed to it. Pumps contain a lot of elements where textured surfaces can be used. The article concentrates on the selection of operating parameters of a picoseconds laser used to produce texturing in elements made of steel, bronze and silicon carbide.

Preliminary studies have shown that signal behavior in ICP/MS is quite different from that in ICP-OES. This is particularly true for the manner in which ICP operating parameters affect the responses of elements detected, and results from behavior occurring both in the interface and in the mass spectrometer. This paper describes in detail the response of a commercially available instrument (VG PlasmaQuad) to variations in several important operating parameters. The effects of nebulizer flow rate, rf plasma power, and sampling depth on ion populations, on ratios of singly charged to doubly charged ions, and on singly charged ions to oxide and hydroxide ions are described for selected elements. A comparison is also made of the results obtained with the present instrument, with data published from other commercial instrumentation.

Ultimate resolution in the scanning electron microscope is determined not only by the diameter of the incident electron beam, but by interaction of that beam with the specimen material. Generally, while minimum beam diameter diminishes with increasing voltage, due to the reduced effect of aberration component and magnetic interference, the excited volume within the sample increases with electron energy. Thus, for any given material and imaging signal, there is an optimum volt age to achieve best resolution.In the case of organic materials, which are in general of low density and electric ally non-conducting; and may in addition be susceptible to radiation and heat damage, the selection of correct operating parameters is extremely critical and is achiev ed by interative adjustment.
