Induction heating facilitated coating systems and processes for pipes overcome corrosion and erosion of the pipes at extreme temperatures and pressures in applications including oil and gas downhole tubulars and pipelines as well as processing facilities. Being based on vitreous fused inorganic compounds, the present invention achieves very high corrosion resistance at remarkably modest cost. Attractive economics and immunity to chlorides and moisture permeation at extreme concentrations and temperatures also make it well suited to desalination plants and potable water piping applications. Due to its extreme temperature resistance, it also is very well suited for geothermal wells. Additionally, due to its characteristic smooth durable surface, the present invention is ideally suited for applications involving the opposite of corrosion, namely scaling problems, such as fouling in sewage systems and scale buildup in heavy oil wells.

The invention relates to a method for producing a sensor element for a potentiometric sensor, comprising: conditioning at least one region of a substrate, which consists of copper or a copper-based alloy having a mass fraction of at least 60% of copper, for producing an oxide layer comprising monovalent copper (Cu(I)), and applying an ion-selective, in particular a pH-selective enamel layer at least onto the region of the substrate.

Methods for fabricating wires insulated by low porosity glass coatings are provided, as are high temperature electromagnetic (EM) devices containing such wires. In embodiments, a method for fabricating a high temperature EM device includes applying a glass coating precursor material onto a wire. The glass coating precursor material contains a first plurality of glass particles having an initial softening point. After application onto the wire, the glass coating precursor material is heat treated under process conditions producing a crystallized intermediary glass coating having a modified softening point exceeding the initial softening point. The crystallized intermediary glass coating is then infiltrated with a filler glass precursor material containing a second plurality of glass particles. After infiltration, the filler glass precursor material is heat treated to consolidate the second plurality of glass particles into the crystallized intermediary glass coating and thereby yield a low porosity glass coating adhered to the wire.

A method of manufacturing a tubular member for an exhaust gas treatment device according to at least one embodiment of the present invention, the tubular member including a tubular main body made of a metal and an insulating layer formed on at least an inner peripheral surface of the tubular main body, the insulating layer containing glass, includes steps of: forming a coating film by bringing a coating liquid for insulating layer formation supplied to the tubular main body into contact with a contact member; and firing the coating film to obtain the insulating layer.

The present disclosure relates to a treating method of a metal surface, and a coating method thereof using the same. A treating method of a metal surface may include grinding solid carbon dioxide and then spraying the ground solid carbon dioxide onto a metal surface. After spraying the ground solid carbon dioxide, irradiating short-wavelength ultraviolet rays on the metal surface, thereby removing foreign substances attached to the metal surface, reforming the metal surface into a hydrophilic surface and improving wettability of a coating material.

A dry composition comprising 2 to 30 weight percent R.sub.2O (wherein R.sub.2O is an alkali metal oxide, K.sub.2O, Na.sub.2O, Li.sub.2O or mixtures thereof); 10 to 74 weight percent SiO.sub.2; and 23 to 79 weight percent B.sub.2O.sub.3. Aqueous solutions and/or colloidal suspensions (thus referred to as solution-suspensions) are used to blend to give a liquid-binder which, on drying, contains the composition within the range given above in the R.sub.2O—SiO.sub.2—B.sub.2O.sub.3 system. The dry composition is mixed with sufficient H.sub.2O to form the solution-suspensions. As described herein H.sub.2O may also be present in some additional additive.

The present invention relates to an abradable coating for a turbine engine part, characterized by the fact that said coating includes a layer made of an abradable material, the surface asperities of which are filled with thermally bonded ceramic grains, forming a smooth, free surface having a low roughness.
