量を比重で除して換算され、体積比が求められる。The particle size of these powders is not particularly limited. The amount of the solid lubricant to be blended is preferably 20 to 30% by volume based on the epoxy resin (including the curing agent). Here, each volume is converted by dividing the weight by the specific gravity, and the volume ratio is determined.

A cylindrical specimen (5) is fixed to the shaft end of the rotating shaft (2) with a set screw (6), and a sample (7) is fixed to the end face of the cylindrical specimen (5) with an adhesive. Spindle (8)
is inserted into the hole (10) of the block (9) and is lubricated with grease to move freely in the axial direction. The tip of the column (12) of the air cylinder (11) is in contact with one end of the spindle (8). A round rod-shaped mating specimen (13) is fixed to the other end of the spindle (8) with a set screw (14).

料（７）と相手試片（１３）が互いに摩擦する。In the above wear tester, when compressed air is sent to the air cylinder (11), the spindle (8) is pushed to the left, and the sample (7) and the mating specimen (13) are pressed against each other. At this time, the specimen (7) is rotating, and the opposing specimen (
13) is not rotated by the rotation stopper (15), so the sample (7) and the mating specimen (13) rub against each other.

摩耗量は試験の前後の試料（７）の厚さをマイクロメー
タで測り、次式により比摩耗量Ｗが算出される。The amount of wear is measured by measuring the thickness of the sample (7) before and after the test with a micrometer, and the specific amount of wear W is calculated using the following formula.
式中、δは試料（７）の厚さの減少量、ｎは回転軸（２
）の回転数、しは試験時間である。In the formula, δ is the amount of decrease in the thickness of the sample (7), and n is the rotation axis (2
) is the rotational speed, and shi is the test time.
