Abstract: A method for surface engineering a metal substrate involves mixing precursor powders with a polymer binder to create a coating mix and coating the substrate with the coating mix. The substrate is then heated via induction heating, with the frequency and duration of the heating being controlled so as to cause a reaction of the precursor powders to create one or more types of ceramics or intermetallics, evaporate the polymer binder, melt a portion of the substrate, and cause the synthesized compounds to mix with the substrate and form a compositionally graded surface modification. The compound(s) created by the reactions are mixed with molten portion of the substrate and upon re-solidification of the substrate, are distributed at decreasing percentages along a depth of the substrate so that their content varies from 100% at a surface of the substrate to 0% at a defined depth of the substrate.

Abstract: The present invention concerns the down hole motors used in the oil prospecting industry to drive drill bits for drilling the ground at great depths. The down hole motor (1) comprises a drive shaft (5) held in the motor body (3) by an axial thrust bearing (6) and by a radial bearing (7). The radial bearing (7) is a tubular member whose interior surface is coated with an anti-abrasion layer (11) formed by laser-assisted facing directly inside an alloy steel radial bearing body (10). The thickness of the facing layer is then reduced by removing material by means of a cutting tool. This produces a radial bearing (7) that is relatively insensitive to drilling mud and confers great reliability on the down hole motor (1).

In the formation step, the dispersion which has been irradiated with ? rays is applied to an electrode plate and then dried, and the fine polytetrafluoroethylene particles are sintered to form a polytetrafluoroethylene layer on the electrode plate. In the charging step, the surface of the polytetrafluoroethylene layer is subjected to a charging treatment.

Abstract: Certain examples relate to improved methods for making patterned substantially transparent contact films, and contact films made by such methods. In certain cases, the contact films may be patterned and substantially planar. Thus, the contact films may be patterned without intentionally removing any material from the layers and/or film, such as may be required by photolithography. In certain example embodiments, an oxygen exchanging system comprising at least two layers may be deposited on a substrate, and the layers may be selectively exposed to heat and/or energy to facilitate the transfer of oxygen ions or atoms from the layer with a higher enthalpy of formation to a layer with a lower enthalpy of formation. In certain cases, the oxygen transfer may permit the conductivity of selective portions of the film to be changed. This advantageously may result in a planar contact film that is patterned with respect to conductivity and/or resistivity.
