*The following suggestions are provided as a starting point for using the Taber Rotary Abraser to evaluate different materials. Based on the manufacturers recommendations, the abrading wheels should be refaced prior to each test and a consistent vacuum nozzle height should be used (measured off the specimen surface). Other factors to consider include specimen conditioning, environmental conditions, vacuum suction level, specimen cleaning, and test cycles.

Aluminum Anodized Finish

Specimen: 4 inches square or diameter with ¼ inch center hole
Wheels and Load: CS-17 with 500 or 1000 gram load
Alternate Wheels and Load (1): H-18 or H-10 Calibrade with 250 or 500 gram load
Alternate Wheels and Load (2): H-38 Calibrade with 1000 gram load
Evaluation: Visual end point, indicated by the first deep abrasion marks or spot breakthrough as the wheel wears through the hard oxide coating into the soft aluminum; or weight loss method

Steel

Specimen: 4 inches square or diameter with ¼ inch center hole
Wheels and Load: H-10 or H-18 Calibrade with 500 or 1000 gram load
Evaluation: Weight loss method

Electroplate Chrome over Nickel

Specimen: S-16 specimen plates, plated in the usual fashion including the chrome flash
Wheels and Load: CS-10 Calibrase with 500 or 1000 gram load
Evaluation: By comparison of the number of wear cycles necessary for penetration to the nickel coating with that of a standard specimen material tested under identical conditions.
Remarks: The color difference between the nickel and chrome is so slight that it is necessary to prepare and use an indicator solution that will blacken the nickel but not attack the chrome. At intervals during the test, moisten the wear path with the solution applied with a cotton swab on the end of a stick. Discoloration indicates that the abrading wheels have penetrated the chrome deposit. Clean the solution from the specimen before resuming the test.

Electroplate Nickel over Brass (or Copper)

Specimen: S-16 specimen plate, plated in the usual fashion
Wheels and Load: CS-10 Calibrase with 500 or 1000 gram load
Evaluation: By comparison of the number of wear cycles necessary for penetration to the brass (or copper) with that of a standard specimen material tested under identical conditions.
Remarks: The contrasting color of copper permits the end point to be detected visually without an indicator solution. If a sharper indication is desired, a formula that discolors copper but not nickel may be used.

Electroplate Nickel Plated Steel

Specimen: S-16 specimen plate, plated in the usual fashion
Wheels and Load: CS-10 Calibrase with 500 or 1000 gram load
Evaluation: By comparison of the number of wear cycles necessary for penetration to the steel with that of a standard specimen material tested under identical conditions.
Remarks: Use copper sulfate as an indicating solution.

General Notes

  • To generate useful data, specimens must be flat. Specimens of uneven thickness should be shimmed so that the top surface runs true.
  • A Drive Pin Type Holder (E140-19) can be used to eliminate the need for the center hole. Specimens are attached with S-37 or S-37-1 mounting sheets and two driving pins prevent slipping.
  • The recommended specimen thickness is 6.35mm ( inch). Using the S-21 Extension Nut, specimens up to 12.7mm ( inch) in thickness can be evaluated. An Arm Height Extension modification (available from Taber Industries or Taber distributors) will permit testing up to 40mm in thickness.
  • To subject specimens to a wet abrasion test, the Rimmed Specimen Holder (E140-75) can be used. This is useful to determine the effect of absorbed and / or surface moisture on abrasion resistance.
