Abstract:
An electrode for an electrical-discharge surface-treatment method is molded with a metallic powder or a metallic compound powder having an average grain diameter of 6 micrometers to 10 micrometers. A coat on a surface of a workpiece is formed with a material constituting the electrode or a substance that is generated by a reaction of the material due to a pulse-like electrical discharge. The coat is built up with a material containing metal as a main constituent under conditions of a width of a current pulse for the pulse-like electrical discharge in a range of 50 microseconds to 500 microseconds and a peak of the current pulse equal to or less than 30 amperes.

Provided is a method for forming a high-hardness inorganic coating layer, which is capable of providing a coating layer having abrasion resistance, chemical resistance, contamination resistance, high hardness and non-flammability on a surface of a metal or non-ferrous metal substrate at room temperature. The method comprises cleaning a substrate surface to remove impurities; subjecting a substrate surface to ultrasonic cleaning; preparing a high-hardness inorganic coating composition; coating the substrate surface with the high-hardness inorganic coating composition to form a high-hardness coating layer; drying the high-hardness coating layer; and heating the substrate at a temperature of 250 to 27O0C to cure the high-hardness coating layer.

A process and apparatus prints images. The process provides an imaging surface; an array of styli opposed to the imaging surface; and a flow of liquid ink containing charged ink particles in the ink between the imaging surface and the array of styli. A voltage bias is established between at least one stylus in the array of styli and the imaging surface. The voltage bias plates at least some charged ink particles onto the imaging surface in response to the voltage bias.
Abstract:
The invention relates to an operating method for an atomiser (1) for the coating of structural components, particularly of vehicle body parts, with the following steps: Application of a spray jet of a coating agent through the atomiser (1); discharge of a first guide air flow (11) for the formation of a spray jet; determination of at least one application parameter (η, γ, T, BC/CC, Qvarnish, n, U,) which reproduces a property (η, γ, T, BC/CC) of the applied coating agent or an operating variable (Qvarnish, n, U) of the atomiser (1) as well as influencing of the first guide air flow (11) as a factor of the application parameter (η, γ, T, BC/CC, Qvarnish, n, U,). Within the framework of the invention, there is the alternative option that fluctuations of the application parameters and, based thereon, variations of the spray jet width are taken into account by means of an adaptation of the path spacing (d) between the adjacent coating agent paths for the purpose of keeping the path overlapping constant. Furthermore, the invention comprises a corresponding coating apparatus.
Abstract:
Light reactive deposition uses an intense light beam to form particles that are directly coated onto a substrate surface. In preferred embodiments, a coating apparatus comprising a noncircular reactant inlet, optical elements forming a light path, a first substrate, and a motor connected to the apparatus. The reactant inlet defines a reactant stream path. The light path intersects the reactant stream path at a reaction zone with a product stream path continuing from the reaction zone. The substrate intersects the product stream path. Also, operation of the motor moves the first substrate relative to the product stream. Various broad methods are described for using light driven chemical reactions to produce efficiently highly uniform coatings.
Abstract:
A system for treating a surface to prevent or limit offensive odors and/or microbiological activity and improve indoor air quality includes electrostatically charged particles of anatase titanium dioxide and a substrate or surface on which these particles are received. The electrostatic charging of the particles, in conjunction with the substrate being oppositely charged, provides a self-leveling effect to the particles. The particles may be incorporated into an HVAC system defined by ductwork in which untreated air including organic matter flows, is treated, and is ejected as clean air. Methods of treating surfaces or fluids containing organic matter include providing electrostatically charged particles of anatase titanium dioxide and contacting the organic matter therewith to initiate photocatalytic oxidation processes in which the organic matter is broken down into less offensive constituents such as carbon dioxide and water.
