Abstract: A method of measuring a friction coefficient of a surface of a specimen includes: obtaining surface information of the specimen by using an atomic force microscope (AFM); calculating data of a friction coefficient of the surface of the specimen by using the surface information of the specimen; and mapping the data of the friction coefficient of the specimen to an image. The method of measuring a friction coefficient of a surface of a specimen may prevent a probe part of an atomic force microscope from being worn out and secure high reliability of the friction coefficient value by correcting the atomic force microscope using a specimen to be actually measured and measuring a fiction coefficient at the same time.

Abstract: Disclosed is a surface treatment method for producing a coating layer, which improves surface properties (e.g., low friction wear-resistance) of the coating layer at high temperature.

Abstract: Disclosed herein is a method and apparatus for manufacturing a panel for a vehicle. When a steel sheet is machined to form a panel for a vehicle, a blanking-texturing machine conducts a blanking process for cutting the steel sheet and a texturing process for forming depressions in the steel sheet at the same time. Therefore, the present invention reduces the number of manufacturing processes, thus enhancing the productivity, and reducing the production cost and provides a steel sheet with uniform depressions across the surface of the steel sheet, thereby reducing the coefficient of friction during the pressing process consistently.
