13、or the Corrosion Protection of Steel” is issued to meet a criticalindustry and government need.Thermal spray coatings (TSCs) are used extensively for the corrosion protection of steel and iron ina wide range of environments. The corrosion tests carried out by the American Welding Society(1)and the m

14、arine-atmosphere performance reports of ASTM(2)and the LaQue Center for CorrosionTechnology(3)confirm the effectiveness of flame-sprayed aluminum and zinc coatings over longperiods of time in a wide range of hostile environments. The British Standards Institution “Code ofPractice for the Corrosion P

15、rotection of Steel”(4)specifies that only TSCs give protection for morethan 20 years to first maintenance for the 19 industrial and marine environments considered andthat only sealed, sprayed aluminum or zinc gives such protection in seawater immersion or splashzones.This standard may be used by own

16、ers, and design, fabrication, and maintenance engineers todetail and contract for the application of TSCs for the preservation and maintenance of steelstructures. This standard may also be used by TSC inspectors and TSC applicators to developand maintain application procedures, equipment inventory,

17、and an operator-training program.This standard presents the basic need-to-know information for the application of quality TSCs.Appendixes present amplifying information.

30、uired equipment, application procedures, and in-pro-cess quality control (QC) checkpoints are specified. Thisstandard may be used as a procurement document. Ap-pendix A presents a fill-in-the-blanks model procurementspecification. The flow diagram in Figure 1 provides anoverview of the thermal spray

31、 coating process presented inthis standard.Figure 1: Thermal Spray Coating ProcessNot included in this standard are requirements for designand fabrication, thermal spray equipment qualification, coat-ing selection, and operator and inspector certification. Forsuccessful thermal spray application, th

32、e steel structure andcomponents should be designed and fabricated accordingto NACE Standard RP0178.(5)Additional considerationshould be given to weldments whose oxyfuel cut edges mayaffect hardness which may preclude adequate profile depth.1.2 SafetyThe basic precautions for thermal spraying are ess

33、entiallythe same as for welding and cutting. Information on safetycan be found in the Safety Chapter in AWS Thermal Spray-ing: Practice, Theory, and Application; ANSI Z49.1, Safetyin Welding, Cutting; and Allied Processes; and NFPA 58,(6)Standard for the Storage and Handling of Liquefied Petro-leum

34、Gases. Safety precautions can also be found in themanufacturers equipment technical instructions and manu-als and the feedstock Material Safety Data Sheet. Thisstandard may involve hazardous materials, operations, andequipment. This standard does not purport to address all ofthe safety problems asso

35、ciated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applic-ability of regulatory limitations prior to use.Potential thermal spraying hazards include exposure tovapors, dust, fumes, gases, noise (from the sp

36、ray gun), andarc ultraviolet (UV) radiation. Additionally, improperly usedthermal spray equipment can create potential fire and explo-sion hazards from the fuel and carrier gases and a potentialelectrical shock hazard from the electrical and electronicequipment and charged wire spools. To minimize h

37、azards,proper safety precautions shall be followed. Operators shallcomply with the procedures in the safety references, themanufacturers technical manuals, and the material safetydata sheets.Thermal spraying can be a completely safe process whenperformed by an operator who follows the recommendedpre

38、cautionary measures, has a proper understanding ofthermal spraying practices, and has knowledge, skill, andexercises care in using thermal spray equipment.1.3 Units of MeasureThis specification makes use of both the International Sys-tem (SI) and U.S. Customary units. The measurements arenot exact e

39、quivalents; therefore each system must be usedindependently of the other without combining in any way._(5)NACE standards can be obtained from NACE International, 1440 South Creek Drive, Houston, TX 77084-4906.(6)Available from the National Fire Protection Association, 1 Batterymarch Park, P.O.
