SCOPEThis specification defines the pro

2、perties of a filled PTFE dry filmlubricant.2. APPLICATIONThis specification was released originally for film used to provide lowfriction, low wear properties without lubrication, for parts such as thecarburetor override lever.3. REQUIREMENTS3.1 PREPARATION AND TESTING OF PANELSFor initial approval a

3、nd at intervals established by QualityControl.3.1.1 CRLC steel panels. Panels are to be zinc plated plusdichromate per ESF-M1P5-A. The film shall be applied byspray and cured 1 h at 121 C metal temperature. Analternate cure is 45 minutes at 135 C. This coating may beapplied to other substrates such

4、as brass, steel, etc. butmust meet this specification regardless of substrate.3.1.2 The coating shall be uniform in color, hiding power andcoverage and free of obvious imperfections as determined byunaided visual examination. Shall also be smooth to thetouch and free of cracks when observed at a mag

6、s, para 3.1.2, 3.1.3, 3.1.4,3.1.5, and 3.1.6 are to be run on finished parts. On anypart with a configuration which does not allow a test to berun, that requirement shall be waived.ENGINEERING MATERIAL SPECIFICATIONESF-M13P6-APage 2 of 2The above requirements for both thickness and salt sprayapply o

7、nly to significant surfaces. The specified coatingthickness shall be required only on such surfaces of partsother than threads or holes, as can be touched by a sphere0.5 in (12.7 mm) in diameter unless otherwise noted ondrawings. On other surfaces such as those of holes,recesses, threads, etc., wher

8、e a controlled deposit cannotbe obtained under normal coating conditions, the aboverequirements do not apply. Acceptance or rejection ofparts submitted to this specification will be based onthickness and salt spray results on significant surfaces.3.2.2 Infrared SpectrophotometryFord Motor Company, a

9、t its option, may conduct infraredanalysis of material/parts supplied to this specification.The curves established for initial approval shallconstitute the reference standard and shall be kept on fileat Central Laboratory. All samples shall produce curvesthat correspond to the reference standard whe

10、n tested underthe same conditions as those specified on the master curve.3.3 SUPPLIERS RESPONSIBILITYMaterial supplied to this specification must be equivalent to thatoriginally approved. Changes in formulation or processing shallnot be made without prior approval as described in SupplierProcedure I

11、-A.4. APPROVAL OF SUPPLIERSSuppliers to this specification must be approved by the affected productengineering office. Procedure for gaining approval of a specificmaterial to a new/existing ES-M specification is contained in SupplierProcedure I-A. Approved new suppliers will be added to the EngineeringMaterials Approved Source List.5.
