This standard is issued under the fixed designation C; the number 1 This test method is under the jurisdiction of ASTM Committee B08 on Metallic. ASTM C determines the bonding strength of thermal spray coatings. ASTM Standard C, “Standard Test Method for Adhesion or Cohesive Strength of Flame-Sprayed Coatings,” is widely used in industry and research for .

ASTM C is used for comparing adhesion or cohesion strengths of coatings of similar types of thermal spray materials. It is useful for comparing adhesion or cohesion strengths of coatings of similar types of thermal spray materials. The assembly is pulled at a constant speed between 0.

Work with us to find the right equipment for your ASTM standard. ASTM C determines the degree of adhesion or bonding strength of a coating to a substrate or the cohesion strength of the coating in a tension normal to the surface. Expensive equipment is then required to carry out this inflexible test method. Link to Active This link will always route to the current Active version of the standard.

ASTM C633 Thermal Spray Adhesion Testing

ASTM C testing standard is often specified as a default standard. How can we help you? An electromechanical universal test machine can be used to measure cohesion strength of a coating. Next Checking to see if you are a returning visitor…. Because of residual stresses in thermal spray coatings, actual strength depends upon the shape of the particular coated part.

The entire ASTM C specification should be reviewed prior ashm performing the test to ensure correct substrate surface preparation, application of coatings and test speeds.


By means of our testing expertise and modular product design, we will help find the testing solution that is right for you. Further development may establish that thin layers of certain types of especially dense coatings may be tested satisfactorily.

Higher temperature testing is restricted by the need for a suitable adhesive bonding agent. Give one of our application engineers a call today for help with creating the best axtm and testing wstm according to ASTM C Thermal spray coating materials include ceramics and metals.

The maximum force is then normalized over the cross-sectional area to give adhesion or cohesion strength of the thermal spray. We offer c363, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

It is the responsibility of the user of this standard to establish appropriate safety and health limitations prior to use.

If failure is entirely at the coating-substrate interface, then the result is referred to as the adhesion strength. In some case a coating is formed of different spray materials.

ASTM C – DFD® Instruments

The purpose of this standard is to aid in testing bond c33 of thermal spray coatings. Maximum pull stress is recorded. It is important to review ASTM C in order to fully understand the test setup, procedure, and results requirements. To spray-coat a cylinder end is not necessarily a good representation of spraying another surface; If a coating adhesion on a particular substrate is to be investigated special astj cylinders of the same material need to be made; The test procedure is slow and cumbersome; Not everybody has access to a tensile testing machine, and they can be very expensive to purchase The Solution The PAT adhesion tester has addressed all these problems.

ASTM C Thermal Spray Adhesion Testing – ADMET

ASTM C ASTM C is a c63 method used in quality control, acceptance testing, developing thermal spray coatings and comparing adhesion or cohesion of adhesion thermal spray coating materials. In some cases, a coating is formed of different c363 materials, such as an oxide layer sprayed onto a sprayed metal-bonding layer.

The Problems The method works but is associated with a number of drawbacks: We are confident that we have what you are looking for.

How bad is it? The test consists of coating one face of a substrate fixture, bonding this coating to the face of a loading fixture, and subjecting this assembly of coating and fixtures to a tensile load normal to the plane of the coating. The method works but is associated with a number of drawbacks:
