Abstract: Provided is a surface treatment method, including: preparing a composite comprising chromium (Cr) of about 95 to 98 atomic percents and copper (Cu) of about 2 to 5 atomic percents with respect to the total number of atoms in the composite; and forming a coating layer comprising Cr of about 30 to 40 atomic, Cu of about 2 to 5 atomic percents, with respect to the total number of atoms of the coating layer, and N constituting the balance of the atoms of the coating layer, by sputtering from the composite in a nitrogen-containing atmospheric gas. Further, provided is a vehicle part, surface of which is treated with the same method.

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: An exemplary embodiment provides a device of moving a low ignition propensity cigarette paper which includes an air moving body portion having a curved surface, an inlet injecting air, and a plurality of outlets disposed at the curved surface to discharge the air, in which the low ignition propensity cigarette paper having a coating portion is floated and turned by the air discharged from the plurality of outlets.

Abstract: A low ignition propensity cigarette paper includes a first coating layer disposed in a combustion section combusted by smoking, and a second coating layer disposed in a cigarette butt section where smoking is finished, wherein a basis weight of the first coating layer is smaller than a basis weight of the second coating layer.
