Terminology3.1 Definitions:3.1.1 dry solid film lubricants, ndry coatings consisting oflubricating powders in a solid matrix bonded to one or
8、bothsurfaces to be lubricated.4. Summary of Test Method4.1 The dry solid film lubricant is applied to anodizedaluminum panels, immersed in water or other fluids for 24 h,and then wiped dry. A strip of masking tape is pressed onto thepanel and removed abruptly. Film removal exposing thesurface of the
9、 metal panel is the criterion for failure.5. Significance and Use5.1 Effective solid film lubricant coatings must adhere tosurfaces to provide adequate lubrication in applications withrestricted access where fluid lubricants cannot easily be replen-ished. Loss of coating adhesion results in metal to
10、 metalcontact causing significant wear of contacting surfaces. Adhe-sion is critical to the performance of the solid film lubricant.Examples of solid film lubricant applications include fasteners,bearings and sliding members in automotive, aircraft, andaerospace hardware.5.2 This test method is inte
11、nded to determine the adhesionof solid film lubricant coatings when submitted to contact withwater and other fluids. Results of this test provide an indicationof the suitability of the lubricant coating in applications wherecontact with water or other fluids is likely.6. Apparatus6.1 Rubber Covered

20、 available com-mercially.6It must be less than 12 months old. Its adhesion strength maybe checked by using Test Methods D1000 to ensure uniformity.7.3 Water, conforming to Specification D1193.7.4 Solvent, safe, non-filming, nonchlorinated.NOTE 2Petroleum distillates and hexanes formerly used as solv
21、ents inthis test method, have been eliminated due to possible toxic effects. Eachuser should select a solvent that can meet the applicable safety standardsand still thoroughly clean the parts.8. Test Sample and Specimen Preparation8.1 Have a sufficient quantity of solid film lubricant toperform the
22、test. Prepare the test panels as follows:8.1.1 Liquid-degrease in a solvent conforming to the re-quirements of 7.4. The panels shall be considered clean whenthe surface maintains a continuous water film for a period of atleast 1 min after immersion in clean water at a temperature of38 C 6 3 C (100 F
23、 6 5 F) in accordance with 1.1 of TestMethod F22.8.1.2 Coat the test panels with dry solid film lubricant bymeans of spraying or an equivalent method to produce a dryfilm thickness between 0.005 mm and 0.013 mm (0.0002 in.and 0.0005 in.) and cure the film.8.1.3 In most cases, curing shall be carried
24、 out according tothe particular manufacturers specifications. If such instruc-tions are not provided, cure the film by air drying for 6 h at26.7 C 6 3 C (80 F 6 5 F) or by air drying for 30 min at26.7 C (80 F) followed by 1 h in an air-circulating oven at149 C (300 F).8.1.4 Measure the dry film thic
25、kness using a micrometer orequivalent gage.9. Procedure AFor Resin-Bonded Coatings9.1 Immerse the panels in a beaker of water to a depth ofhalf the length of the panel for 24 h at room temperature. Takecare to ensure that the panels are separated.9.2 Remove panels and wipe dry with a soft, dry, lint
26、-freecloth. Air dry the panels at 25 C 6 3 C (77 F 6 5 F) at arelative humidity between 45 % and 55 % for 1 h 6 0.1 h.9.3 Using the stylus, make two parallel scratches 25 mm(1 in.) apart on the panels (within 1 min after drying).Scratches shall be through the films (break through), parallel tolong d
27、imension of panel, and pass through both the water-immersed section and dry section.9.4 Place a piece of masking tape lightly over the panel,perpendicular to the scratches, and press the tape down withtwo passes of the roller. The panel shall be resting on a hardsurface and minimum pressure shall be
28、 exerted by the operatoron the roller during the rolling operation. The tape shall beplaced over both the immersed and dry sections.9.5 Remove the tape with an abrupt motion.9.6 Examine the test panel visually.9.7 Report loss of adhesion of the film from the surface ofthe panel. Film removal exposin
29、g areas of the metal surface isindicative of poor adhesion characteristics.9.8 Report the conditions of application and of curing thecoating.10.

Permit the panels to remain inthe test fluid at 74 F 6 2 F (2
31、3 C 6 1 C) for 24 h 6 0.25 h.11.2 Remove the panels from the test fluid and allow themto drain for 1 h 6 0.1 h. Dip each panel in three separate rinsesof a solvent, conforming to the requirements of 7.4, and permitthem to air dry for at least 1 h.11.3 Proceed in accordance with 9.3 9.8.NOTE 3Procedu
32、re C is based on military requirements for resistanceto fuels, solvents, lubricants, and hydraulic fluids which are readilyremoved by the solvent indicated in 7.4. If it is desired to apply it tochemical rocket propellants or other fluids immiscible with this solvent, orwhich are volatile enough to
33、need no solvent, appropriate variations arerequired. These shall become part of the test report, as shall theidentification of the fluids used.12.
