摘要:
A method for a structure 120 having a countersunk fastener head 112 includes forcing an aliphatic urethane surfacer 430 into a void 124 around the fastener head. The method is applicable to an aircraft 200 comprising a composite skin 420 and a plurality of fasteners 410 having heads 412 countersunk in an exterior surface of the skin 420.
摘要:
A method for depositing a coating includes creating a vacuum within an interior volume of a tubular structure, wherein the tubular structure also includes an internal surface. Gas is supplied to the interior volume of the tubular structure, wherein the gas includes a plasma precursor in the gas phase. The tubular structure is biased relative to ground. Plasma having a density is formed and cyclically positioned along the length of the tubular structure. Positive ions of the plasma precursor gas are generated and are deposited on the internal surface forming a coating on the internal surface, wherein the coating exhibits a water contact angle of greater than 120°.

摘要:
An anti-fouling composition contains from 55-80% by weight copper flake or cuprous oxide, 10-30% by weight of a high molecular weight water resistant acrylic resin, and 0.5-5% by weight fumed silica and/or fluorinated resin. Most compositions are non-ablative. Copper flake of a particle size 15-25 microns is preferred for most applications. Some of the compositions are particularly useful for providing protection against fouling for boat propellers.

A manufacturing method of a rotating machine (100) includes: a casing forming process (S0) of forming a casing (1) of the rotating machine (100) having openings (5, 6, 10, 11) and suctioning and discharging a fluid (F); a surface activating process (S2) of supplying and discharging a pretreatment liquid (W1) into and from the casing (1) through the openings (5, 6, 10, 11) and activating an inner surface (1a) of the casing (1); a preheating process (S4) of supplying and discharging a preheating liquid (W2) into and from the casing (1) through the openings (5, 6, 10, 11) and preheating the casing (1); a plating process (S5) of supplying and discharging a plating liquid (W3) into and from the casing (1) through the openings (5, 6, 10, 11), and circulating the plating liquid to plate the inner surface (1a) of the casing (1); and an assembling process (S7) of providing a rotating body (3, 4) such that the rotating body is covered from an outer peripheral side by the plated casing (1). In the surface activating process (S2), the preheating process (S4), and the plating process (S5), when the liquid level of each of the liquids used in each process is vertically changed in the casing (1), each of the liquids is supplied to the inner surface (1a) of the casing (1) in a range above the liquid level by a treatment liquid auxiliary supply device (18).
摘要:
The invention relates to a process for depositing a compact film of particles (4) on the internal surface (10) of a part (2), comprising the following steps: a) placing the part (2) in a carrier liquid (6); b) generating a flow of carrier liquid (44) into the hollow (8) of the part in the direction of the surface (18) of the carrier liquid, so as to create a protuberance (50); c) dispensing the particles (4) in order to form a compact film floating on the liquid (6) between a contact line (20) and an upstream front (6) of particles; and d) transferring the film (4) onto the internal surface (10) by performing a relative displacement between this part (2) and the surface (18) of the carrier liquid, while continuing to dispense particles (4) onto the upstream front (60).
摘要:
Siloxane-based pipe coatings include a hot melt processable siloxane-based elastomeric polymer, and may optionally contain fillers and additives. The siloxane-based elastomeric polymer is a urea-containing segmented copolymer or an oxamide-containing segmented copolymer. The coatings are substantially free of tackifying resins and are non-tacky and non-adhesive until heated to a temperature of at least 50 C.
