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 .

Thermal Spray Technology, Vol. It is adapted particularly for testing coatings applied by thermal spray, which is de? Permissible variation shall be less than 1.

The challenges of testing to this standard are: Next Checking to see if you are a returning visitor…. If failure is entirely at the coating-substrate interface, then the result is referred to as the adhesion strength.

Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Excessive ashm shall c6333 wiped from the assembly with soft paper or cloth.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which x633 may attend. Maximum pull stress is recorded.

NOTE 2—Thermal spray coatings may have an inherent porosity. The substrate generally is a metal, but may be a ceramic, such as an oxide c33 graphite. The design of the loading? The substrate is generally a metal but may be a ceramic.

To ensure the direction of force application is perpendicular to the coated surfaces, ASTM C specifies to use a self-aligning load fixture to attach these substrate cylinders to the test frame. Standard Test Method f If failure is entirely at the coating-substrate interface, then the result is referred to as the adhesion strength.

For certain fundamental investigations, it is suggested that very low cryogenic temperature be used.

The limitation is imposed because an adhesive bonding agent is used in the test. How bad is it?

ASTM C633 Adhesion or Cohesion Strength of Thermal Spray Coatings

A similar, but uncoated, fixture is then glued to the surface of the coating with a suitable adhesive bonding agent. The diameters of the two?

For certain fundamental investigations, it is suggested that very low cryogenic temperature be used. Further development may establish that thin layers of certain types of especially dense coatings may be tested satisfactorily. 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 qstm load normal to the plane of the coating.

Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. A low-power microscope with a magni? The maximum force is then normalized over the cross-sectional area to give adhesion or cohesion strength of the thermal spray.

A layer greater than 0. A recommended method is to use a surface grinder with a magnetic chuck, positioning the rear face of the coated?
