5、013-09 Superseding AMS2530 Tungsten Disulfide Coating, Thin Lubricating Film, Binder-Less Impingement Applied RATIONALE AMS2530A revision includes revised adhesion testing frequency, revises dimensions for thickness and adhesion test specimens, and gives cognizant engineering organization the option
6、 to waive surface finishing by honing prior to coating. 1. SCOPE 1.1 Form This specification covers a coating consisting of tungsten disulfide without binders and not requiring a curing process. 1.2 Application This product has been used typically on metal parts and selected nonmetallic materials (e
7、.g., thermoplastic and thermosetting polymers) where a friction-reducing coating under 0.00002 inch (0.5 m) thick is required and where wear, galling, seizure, and fretting need to be minimized, but usage is not limited to such applications. This lubricating film has been shown to be compatible with
8、 such fluids as reagent grade water, petroleum-based hydraulic fluid, petroleum-based oils and greases, SAE phosphate ester test fluid #1, silicone fluid, unsym-dimethylhydrazine (UDMH)-compatible grease, inhibitied fuming red nitric acid (IFRNA)-compatible grease, solid rocket propellants, nitrogen
9、 tetroxide, liquid oxygen and hard radiation environments. 1.3 Safety - Hazardous Materials While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards that may be
10、involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved. 2. APPLICABLE DOCUMENTS The issue of the following doc
11、uments in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding documen
12、t has been specified, the last published issue of that document shall apply.

16、hall consist tungsten disulfide in a finely powdered, lamellar form. The material shall contain no graphite, molybdenum disulfide, binders or organic constituents so as to be compatible in liquid oxygen systems and hard radiation environments. The coating material, properly applied, shall, without a
17、 curing process, form a lubricating film conforming to the requirements of 3.4 3.2 Preparation 3.2.1 Cleaning The surfaces of the basis material shall be thoroughly cleaned with a procedure capable of removing all polar and non-polar substances including oils and greases as well as any corrosion pro
18、ducts and scale/oxide deposits. The cleaning procedure shall not produce pitting or intergranular attack of the basis metal and shall preserve dimensional requirements. The cleaned surfaces shall be free from oils (including skin oils), greases, dirt, particulate matter or other surface contaminatio
19、n. All parts shall be handled in such a manner as to prevent re-contamination of any surfaces to be coated during the application process. 3.2.2 Surface Finishing Unless otherwise approved by the cognizant engineering organization, surfaces of parts to be coated shall be honed with 5 micron aluminum
20、 oxide powder to prepare the basis material for coating. See 8.2.1. Following honing, surfaces shall be cleaned to remove all residual particles. 3.3 Procedure The coating material shall be applied to all specified surfaces by spraying at high velocity (impinging) under controlled conditions. SAE IN
21、TERNATIONAL AMS2530A Page 3 of 7 3.4 Properties The coating shall conform to the following requirements: 3.4.1 Adhesion A pressure-sensitive-film-backed tape with an adhesion of not less than 45 ounces per inch (0.49 N/mm), shall be applied to a flat surface of a coated specimen, rolled in place, an
22、d rapidly removed in accordance with ASTM D 2510, Procedure B. The lifting of flakes or particles of the coating from the specimen, exposing the basis metal, is not acceptable. A uniform deposit of powdery material clinging to the tape is acceptable. 3.4.2 Thickness Thickness shall be not greater th
23、an 0.00002 inch (0.5 m), determined in accordance with ASTM D 7091 or ASTM B 567 or by a method acceptable to the cognizant engineering organization. 3.4.3 Thermal Stability The coating shall be tested for thermal stability in accordance with ASTM D 2511, except that (a) the extremes of temperature
24、exposure shall range from -188 C or colder to 482 C or hotter and (b) the samples shall be allowed to return to room temperature for a minimum of 5 minutes between the hot and cold exposures. After exposure, the film shall not crack, flake, blister or soften and shall then meet the adhesion requirem
