Designation:B99915Standard Specification forTitanium and Titanium Alloys Plating,ElectrodepositedCoatings of Titanium and Titanium Alloys on Conductiveand Non-Conductive Substrate1This standard is issued under the fixed designation B999;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers the requirements for electrode-posited coatings of titanium and titanium-zirconium alloys onconductive and non-conductive substrates for engineering(functional)uses.The coatings of titanium-zirconium alloysare those that range in zirconium between 10wt%and 14wt%zirconium and are known as“terne”metallic electrodeposits.1.2 This specification applies for both conductive(metallic)substrates and non-conductive(plastics,fibers,carbon foam,etc.)1.3 Electrodeposits of titanium and titanium-zirconium al-loys on aluminum and conductive substrate and nonconductivesubstrate are produced where it is desired to obtain atmosphericcorrosion resistance.Deposits of titanium and titanium-zirconium alloys particularly on aluminum have shown to haveexcellent corrosion protective qualities in atmosphericexposure,especially when under-coated by electroless nickel.Titanium and titanium-zirconium alloy deposits provide corro-sion protection from dilute sulfuric acid,are used for lining ofbrine refrigeration tanks,chemical equipment apparatus,stor-age batteries,and as a wear coating for bearing surfaces.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2B117 Practice for Operating Salt Spray(Fog)ApparatusB183 Practice for Preparation of Low-Carbon Steel forElectroplatingB242 Guide for Preparation of High-Carbon Steel for Elec-troplatingB253 Guide for Preparation of Aluminum Alloys for Elec-troplatingB320 Practice for Preparation of Iron Castings for Electro-platingB322 Guide for Cleaning Metals Prior to ElectroplatingB374 Terminology Relating to ElectroplatingB487 Test Method for Measurement of Metal and OxideCoating Thickness by Microscopical Examination ofCross SectionB499 Test Method for Measurement of Coating Thicknessesby the Magnetic Method:Nonmagnetic Coatings onMagnetic Basis MetalsB504 Test Method for Measurement of Thickness of Metal-lic Coatings by the Coulometric MethodB507 Practice for Design of Articles to Be Electroplated onRacksB567 Test Method for Measurement of Coating Thicknessby the Beta Backscatter MethodB568 Test Method for Measurement of Coating Thicknessby X-Ray SpectrometryB571 Practice for Qualitative Adhesion Testing of MetallicCoatingsB602 Test Method for Attribute Sampling of Metallic andInorganic Coatings1This test method is under the jurisdiction ofASTM Committee B08 on Metallicand Inorganic Coatings and is the direct responsibility of Subcommittee B08.03 onEngineering Coatings.Current edition approved Nov.15,2015.Published December 2015.DOI:10.1520/B0999-15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 B697 Guide for Selection of Sampling Plans for Inspectionof Electrodeposited Metallic and Inorganic CoatingsB727 Practice for Preparation of Plastics Materials for Elec-troplatingB733 Specification for Autocatalytic(Electroless)Nickel-Phosphorus Coatings on MetalB849 Specification for Pre-Treatments of Iron or Steel forReducing Risk of Hydrogen EmbrittlementB850 Guide for Post-Coating Treatments of Steel for Reduc-ing the Risk of Hydrogen EmbrittlementB851 Specification for Automated Controlled Shot Peeningof Metallic Articles Prior to Nickel,Autocatalytic Nickel,or Chromium Plating,or as Final FinishD2982 Test Methods for Detecting Glycol-Base Antifreezein Used Lubricating OilsD3359 Test Methods for Measuring Adhesion by Tape TestD5185 Test Method for Multielement Determination ofUsed and Unused Lubricating Oils and Base Oils byInductively Coupled Plasma Atomic Emission Spectrom-etry(ICP-AES)E127 Practice for Fabrication and Control of AluminumAlloy Ultrasonic Standard Reference BlocksF519 Test Method for Mechanical Hydrogen EmbrittlementEvaluation of Plating/Coating Processes and Service En-vironments3.Terminology3.1 DefinitionsDefinitions of the terms used in thi
