ASTM G32 Captivation Erosion Test Button

The method therefore offers a small-scale, relatively simple and controllable test that can be used to compare the cavitation erosion resistance of different materials, to study in detail the nature and progress of damage in a given material, or—by varying some of the test conditions—to study the effect of test variables on the damage produced.

For specific safety warning information, see 6. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided g332 part of the standard.

Test Method G73 describes another testing approach specifically intended for that type of environment.

It gives guidance on setting up a suitable apparatus and covers test and reporting procedures and precautions to be taken. However, adherence to this test method in all other respects will permit a better understanding and correlation between the results of different investigators.

It gives guidance on setting up a suitable apparatus and covers test and reporting procedures and precautions to be taken. The stationary specimen approach can also be used for brittle materials which can not be formed into a threaded specimen nor into a disc that can be cemented to a threaded specimen, as required for this test method see 7.

The latter may be more suitable for materials not readily formed into a precisely shaped specimen. It permits deviations from some of these conditions if properly documented, that may be appropriate for some purposes. While several investigators have used this approach see X4. The results of either, or anycavitation erosion test should be used with caution; see 5.

Active view current version of standard. In that method, the specimen is fixed within the liquid container, and the vibrating tip of the horn is placed in close proximity to it.

It also specifies standard reference materials that must be used astmm verify the operation of the facility and to define the normalized erosion resistance of other test materials. This is because the compliance of the coating on the specimen may reduce the severity of the liquid cavitation induced by its vibratory motion.

An alternative method for similar purposes is Test Method Gwhich employs asttm cavitating liquid jet to produce erosion on a stationary specimen. It permits deviations from some of these conditions if properly documented, that may be appropriate for some purposes.

The vibration induces the formation and collapse of cavities in the liquid, and the collapsing cavities produce the damage to and erosion material loss of the specimen.

However, adaptations of the basic method and apparatus have been used for such purposes see atm. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This must be considered in planning, conducting and reporting a test program. It also specifies standard reference materials that must be used to verify the operation of the facility and to define the normalized erosion resistance of other test materials.

The vibration induces the formation and collapse of cavities in the liquid, and the collapsing cavities produce the damage to and erosion material ashm of the specimen.

Small differences between two materials are probably not significant, and their relative ranking could well be reversed in another test.

Guide G may be followed in order asfm determine the synergism between the mechanical and electrochemical effects. The result would not be representative of a field application, where the hydrodynamic generation of cavitation is independent of the coating.
