SCOPE 1.1 Scope. This standard covers thermal sp
29、ray processes for machinery repair and corrosion protection of Naval ship machinery, except the spraying of aluminum for corrosion protection which is covered in DOD-STD-2138. This standard does not apply to primary and secondary systems of nuclear ships. Included are requirements for the qualificat
30、ion of thermal spray procedures and operators, requirements and guidance for use of thermal spray material and equipment, quality assurance requirements, and descriptions of applicable qualification tests. 1.1.1 The thermal spray processes covered by this standard are: (a) wire spraying of consumabl
31、e coating material using oxygen-fuel gas, or using two consumable electrodes in an electric arc system, and (b) powder spraying, using oxygen-fuel gas or plasma arc. 1.2 Application. Thermal spray coatings shall be used only for machinery applications specifically permitted herein (see 5.5.2) or for
32、 which prior approval has been obtained from the Naval Sea Systems Command (NAVSEA). 1.2.1 Requirements of this standard pertain only to the thermal spray coatings applied to ferrous and non-ferrous metal substrates. 2.

46、WS A3.0 and OPP. 3.2 The following definitions are applicable to this standard: (a) Blasting. A method of cleaning or surface roughening by a forcibly projected stream of sharp angular abrasive. (b) Bond coat. A preliminary (or prime) coat of material which improves adherence of the subsequent therm
47、al spray deposit. (c) Coating system. One or more thermal spray coatings that are quali- fied for use singly or in combination. An example of a one-coat- ing system is a stainless steel coating applied for restoration of dimensions. An example of a two-coating system is a nickel-base bond coat and c
48、eramic finish coat for a steam seal. (d) Composite powder. Powder particles that are formed by physically combining two or more materials in intimate contact, so that the end particles function as a unit. (e) Electric arc spraying. A thermal spraying process wherein the heat source is an electric ar
49、c struck between two consumable electrodes of a coating material, and compressed gas (usually air) is used to atomize and propel the material to the work piece. (f) v. A thermal spraying process wherein an oxy-fuel gas flame is utilized as the source of heat for melting the coating materials in powder, wire, rod, or cored form. Compressed gas may or may not be used for atomizing and
