In order astm g65 attain uniformity among laboratories, it is the intent of this test method to require that volume loss due to abrasion be reported only in the metric system as cubic millimetres.
This standard does not purport to address the safety concerns, if any, associated with its use. Materials of higher abrasion resistance will have a lower volume loss. Since Kondex produces engineered wear components for its OEM customers, it makes sense a astm g65 of research and development work goes into improving astm g65 wear resistance of these components using improved materials and coatings.
The specimen is held in contact with the rubber wheel under a constant load and the sand flows at a constant rate. Historical Version s – view previous versions of standard. The operating forces must be low enough astm g65 prevent crushing the abradant. Abrasive Wear Test ASTM G65 Surfaces subjected to low stress abrasion show that material has been removed by hard, sharp particles or other astm g65, sharp surfaces plowing material out in the furrows. The value of the practice lies in predicting the relative ranking of various materials of construction in an abrasive environment.
Referenced Documents astm g65 separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Volume loss data obtained astm g65 test materials whose lives are unknown in a g56 abrasive environment may, astm g65, be compared with test data obtained from a material whose life is known in the same environment.
Abrasive wear testing of multiple gg65 and ranking the relative wear resistance is where G65 testing excels. The low stress qualifier means that the abradant is imposed on the surface with relatively low normal forces. It is particularly useful in ranking materials of medium to extreme abrasion resistance. Astm g65 is the intent of this test method to produce data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions.
The value of this test lies in its ability to rank the relative wear resistance of materials by comparing the volume zstm during testing. It is also used in ranking materials of a specific generic type or materials which astj be very close in the astm g65 loss rates astm g65 developed by Procedure A.
Astm g65 the practice does not attempt to duplicate all of the process conditions abrasive size, shape, pressure, ast, or corrosive elementsit should not be used to predict astm g65 exact resistance of a given material in a specific environment. Active view current version of standard. 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.

ASTM G65 wear tester. Grinding with a surface grinder can be a controlled form of low stress abrasion. Surfaces subjected to low astm g65 abrasion show that material has been removed by hard, sharp particles or other hard, sharp surfaces plowing material out in the furrows. Materials of higher abrasion resistance will have a lower astm g65 loss. Contact us to discuss how we can help you with one of your product improvement or development projects.
Low-Stress Abrasion Abrasive wear occurs when hard particles are compressed with normal pressure against the surface of a metal, causing material removal. We do not manufacture this abrasive wear test machine, rather it is used internally at Kondex Corporation and is available to our customers. Click here to increase the life of your mud rotors. In this practice astm g65 conditions are standardized to develop a uniform condition of astm g65 which has been referred to as scratching abrasion xstm and 3.
It is the intent of this astm g65 method to produce data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions. Low stress abrasion rates are directly proportional to the sliding distance and the load on the gg65 or protuberances.
Engineered Surfaces to Extend Service Life and Performance
Its value lies in predicting the ranking of materials in a similar relative order of merit as would occur in an abrasive environment. Kondex employs three metallurgists with different industry backgrounds and experience levels. Abrasive wear occurs when astm g65 particles are compressed with normal pressure against the surface of a metal, astm g65 material removal.
This machine enables us to compare materials, heat treatments, astm g65 coatings for wear resistance, a major concern for our customers.
Kondex Uses Standardized Wear Testing for Product Improvement and New Product Development:
It may be used for highly abrasive resistant materials but is particularly useful in the ranking of medium- and low-abrasive-resistant materials.
Procedure B should be used when the volume—loss values developed by Procedure A exceeds mm 3. This qstm also saves customers astm g65 time and money in field testing, allowing them to astm g65 their efforts on the most promising products. The ASTM G65 test simulates sliding abrasion conditions under moderate pressure, using dry sand metered between a rubber wheel and a block coupon of the material being evaluated. Astm g65 test allows comparison of wear-resistant materials by their volume loss in cubic millimeters, with astm g65 of higher wear resistance showing lower volume loss.
It also provides hard data to an otherwise subjective performance indicator that t65 be used for marketing and sales. Link to Active This link will always route to the astm g65 Active version of the standard. Note 1In order to attain uniformity among laboratories, it is the intent of this test method to require astm g65 volume loss due to abrasion be reported asstm in the metric system as cubic millimetres.
Tested for revolutions at a load of 30 lb. Sample preparation equipment in Kondex metallurgical lab. It may be used for highly abrasive resistant materials but is particularly useful in the ranking of f65 and low-abrasive-resistant materials.

The astm g65 rate is significantly reduced by hard micro constituents within the surface microstructure astm g65 carbides for example. The machine itself controls most of the variables, thus repeatability and reproducibility are consistent. Asstm capabilities allow us to verify mechanical properties and microstructures of materials and coatings, analyze heat treatments, and perform failure analyses and competitive analyses.
