The vibration induces the formation and collapse of cavities in the liquid, and the collapsing cavities asgm the damage to and erosion material loss of the specimen. 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 astn of test variables on the damage produced.

ASTM G32 – 10 Standard Test Method for Cavitation Erosion Using Vibratory Apparatus

This must be considered in planning, conducting and reporting a test asstm. For this reason, the consistency of results between different test methods or under different field conditions is not very good. 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.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The result would not be representative of a field application, where the hydrodynamic generation of cavitation is independent of the coating. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

It permits deviations from some of these conditions if properly documented, that may be appropriate for some purposes. asmt

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. For specific safety warning information, see 6. For specific safety warning information, see 6.

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. The latter may be more suitable for materials not readily formed into a precisely shaped specimen.

While several investigators have used this approach see X4. 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.

Test Method G73 describes another testing approach specifically intended for that type of environment. The inch-pound units given in parentheses are for information only. 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. An alternative method for similar purposes is Test Method Gwhich employs a cavitating liquid jet g332 produce erosion on a stationary specimen.

The results of either, or anycavitation erosion test atsm be used with caution; see 5. Link to Active This link will always route to the current Active version of the standard.

However, adaptations of the basic method and apparatus have been used for such purposes see 9. Guide G may be followed in order to determine the synergism between the mechanical and electrochemical effects. Active view current version of standard. The inch-pound units given in parentheses are for information only. However, adherence to this test method in all other respects will permit a better understanding and correlation asfm the results of different investigators.

This is because the compliance of the coating on the specimen may reduce the severity of the liquid cavitation induced by its vibratory motion. 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, f32 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.
