1、Designation:D610504(Reapproved 2019)Standard Practice forApplication of Electrical Discharge Surface Treatment(Activation)of Plastics for Adhesive Bonding1This standard is issued under the fixed designation D6105;the number immediately following the designation indicates the year oforiginal adoption

2、 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 practice covers various electrical discharge treat-ments to be used to enhance

3、 the ability of polymeric substratesto be adhesively bonded.This practice does not includeadditional information on the preparation of test specimens ortesting conditions as they are covered in the variousASTM testmethods or specifications for specific materials.1.2 The types of discharge phenomena

4、that are used forsurface modification of polymers fit into the general categoryof nonequilibrium or non-thermal discharges in which electrontemperature(mean energy)greatly exceeds the gas tempera-ture.1.3 The technologies included in this practice are:TechnologySectionGas plasma at reduced pressure8

5、Electrical discharges at atmospheric pressure9AC dielectric barrier discharge9.1High Frequency Apparatus9.1.1Suppressed Spark Apparatus9.1.2Arc Plasma Apparatus9.2Glow Discharge Apparatus9.3NOTE1The term“corona treatment”has been applied sometimes inthe literature to the different electrical dischar

6、ge treatment technologiesdescribed in Section 9.This practice defines each electrical dischargetreatment technology at atmospheric pressure presented in Section 9 anddraws the necessary distinctions between them and corona discharge.SeeTest Method D1868 for“corona discharge.”1.4 The values stated in

7、 SI units are to be regarded as thestandard.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,health,and environmental practices and deter-mine the applicability

8、 of regulatory limitations prior to use.Specific hazard statements appear in Section 6.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,G
