ASTM G105 Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests

    ASTM G105 Introduction

    ASTM G105 (Standard Test Method for Conducting Wet Sand/Rubber Wheel Abrasion Tests) offers a convenient way to test the abrasion resistance of metallic materials at controlled laboratory conditions. Abrasive wear is the wear of a material that is caused by hard particles that move across it. So, this test assists engineers in learning the behavior of materials in abrasive conditions. The technique involves standardized slurry conditions and controlled loading to generate repeatable results. Consequently, this test method facilitates quality control, research, and material selection. The results assist engineers in comparing materials and selecting appropriate materials to be used in industrial systems that are subject to wear.

    Get Certified ASTM G105 Testing for Accurate Abrasion Resistance Evaluation

    Abrasion has a direct impact on the life of components made up of metals and alloys, wear-resistant materials, hard-face coatings, etc., and the costs of their maintenance. Thus, precise testing guarantees the quality of the choice of materials. Certified testing assists industries in comparing materials under similar conditions. Additionally, in laboratories, controlled environments are available to accurately test. Consequently, manufacturers enhance the durability of their products and decrease unforeseen failures.

    Scope of ASTM G105

    • Assesses resistance to scratching abrasion.
    • Applies to metals, coatings, and weld deposits.
    • Assists with research, design, and quality control of metallic materials.

    ASTM G105 Equipment and Sample Preparation

    Rubber Wheel AssemblyUses neoprene wheels with controlled hardness for abrasion.
    Slurry ChamberContains quartz sand and water mixture for testing.
    Precision BalanceMeasures specimen weight before and after testing.

    Use of ASTM G105

    • Comparisons of the abrasion resistance of metallic materials.
    • Favors wear-resistant applications.
    • Helps appraise surface treatments and coatings.
    • Minimizes risk of failure in harsh environments.

    What Is Scratching Abrasion and Why Is It Important?

    Scratching abrasion is produced by the movement of hard particles over a surface. This move erases material and undermines the surface in the long-run. Thus, knowing this mechanism assists engineers in coming up with durable components. ASTM G105 replicates this condition in controlled conditions to achieve consistent comparisons.

    Why Does ASTM G105 Report Volume Loss Instead of Mass Loss?

    Materials vary in density, and this influences the mass loss results. Thus, mass loss is translated into volume loss by this standard to compare with it. This model guarantees equitable ranking of materials in terms of real material removal.

    Common Challenges and Troubleshooting 

    Testing errors can be caused by variability in the composition of the slurry or improper cleaning of the specimen. Also, improper wheel hardness or force usage influences outcomes. Surface porous materials can hold on to cleaning agents and cause a problem with the weights. Also, there are irregular wear patterns caused by improper positioning of the specimen. To address these problems, it is necessary that technicians adhere to standard protocols, keep the slurry conditions consistent, and specimen handling uniform. 

    ASTM G105 Testing Technique Process, and Data Collection

    The process of testing starts with the preparation, cleaning, and weighing of the specimen. Next, technicians subject the specimen to abrasion with rotating rubber wheels and slurry. They wash, dry, and weigh the specimen after every cycle. The process is repeated with varying levels of wheel hardness. Lastly, the loss of volume on the basis of density is calculated. 

    Testing Procedure and Requirements

    ASTM G105 is a wet sand/rubber wheel system to generate controlled abrasion. First, the technicians prepare and weigh the specimen. Thereafter, they rub it on a rotating abrasive slurry rubber wheel. Lastly, they determine the loss of materials at the end of several test cycles.

    Analysis Results and Interpretation

    ASTM G105 records abrasion as cubic millimeter (mm3) volume loss. Reduced volume loss is a sign of increased abrasion resistance. Thus, engineers rank the materials based on these values. SI is the main system of the standard. Proper interpretation aids industries in choosing materials applicable in abrasive environments.
