The present disclosure discloses an antimicrobial tape comprising a tape layer, a connection layer, and an antimicrobial layer. The connection layer is disposed on the tape layer, and the connection layer consists of angstrom-level silicon dioxide. The antimicrobial layer is disposed on the connection layer. The tape layer and the antimicrobial layer are connected by the connection layer consisting of angstrom-level silicon dioxide to increase the connection strength between the tape layer and the antimicrobial layer. The tape layer may be used to cover a surface of an object, and the antimicrobial layer is located on an outer surface. Therefore, after a user touching and using the object, the object has been sterilized through the antimicrobial layer of the antimicrobial tape.

A coating architecture is disclosed that includes a substrate having a surface finish R.sub.a of 0.3μ or finer, an intermediate layer overlying and in contact with the substrate; and a solid lubricant layer overlying and in contact with the intermediate layer. The test results of applying the coating architecture to a reciprocating hammer drill utilizing the coating is also disclosed.

The present invention relates to the technical field of material processing and provides a method for making a metal material composite, including: contacting a first surface of a first plate with a second surface of a second plate; placing the first plate and the second plate in a recess in a circumferential direction of a first roller such that a third surface of the second plate contacts a bottom wall of the recess in a circumferential, the third surface being opposite the second surface, the first plate having a greater hardness than the second plate; and controlling a first roller and a second roller to rotate, thereby rolling to combine the first plate and the second plate into a composite plate, where a fourth surface of the first plate contacts a surface of the second roller and the fourth surface is opposite the first surface during the rolling. According to the method for making a metal material composite in the present invention, flashings and burr on the side edges of a composite plate are avoided by placing the first plate and the second plate in a recess for machining.

The present invention provides a composite plate, a composite plate roughening device, and a method for manufacturing a composite plate, and relates to the technical field of metal plate materials. The composite plate includes a first plate and a second plate, wherein a first side surface of the first plate is provided with striations, the first side surface of the second plate and the first side surface of the first plate are rolled to connect, and the striations of which adjacent ones have a pitch of 0.005 mm to 0.03 mm account for more than 90% of all the striations. For the composite plate described in the embodiments of the present invention, the first side surface of the first plate is roughened such that the first side surface of the first plate and/or the first side surface of the second plate is configured with striations, which increases an area of the first plate and the second plate subjected to rolling, whereby the composite plate produced by combining the first plate and the second plate has a higher bonding strength and thus a stronger bonding.

The present invention provides a cell phone frame and a method for manufacturing the same, and relates to the technical field of cell phone accessories. The cell phone frame includes a composite plate, the composite plate encloses a accommodation space for accommodating the cell phone, the composite plate includes a first plate and a second plate, a first side surface of the first plate is provided with striations, the first side surface of the second plate and the first side surface of the first plate are rolled to connect, and the striations of which adjacent ones have a pitch of 0.005 mm to 0.03 mm account for more than 90% of all the striations. According to the cell phone frame provided in the embodiment of the present invention, the first side surface of the first plate is roughened to form striations, which increases the area of the first plate and the second plate subjected to rolling, so that a composite plate produced by combining the first plate and the second plate has a higher bonding strength, thereby ensuring that the cell phone frame is firmer.
