Disclosed is a post-processing method for improving anti-wear and friction-reducing properties of a CrN coating. According to the method, the CrN coating is subjected to a thermal cycling treatment in a temperature range of &#x2212;20&#xb0; C. to 60&#xb0; C. under a humidity environment of 60%-80% R.H. The post-processing method can substantially improve the anti-wear and friction-reducing properties of the CrN coating, so that friction pair parts deposited with the coating achieve a stable operation for a long time.

A scale-style micro-texture electrode wire material and a preparation method therefor and use thereof. In particular, the electrode wire material has a scale-style micro-texture layer on the surface, and the electrode wire material comprises: i) an alloy substrate layer as an inner layer; ii) an interdiffusion layer as an intermediate layer; and iii) a plating layer as an outer layer; and a contact angle of the electrode wire material to a cooling liquid is 105-150&#xb0;. A method for preparing the electrode wire material and a use thereof. Due to the special surface bionic structure, the electrode wire can obviously reduce the cutting resistance and improve the cooling speed, thereby improving the cutting speed and effectively improving the use performance of the electrode wire. The preparation method has the characteristics of simple process and easy for industrial production.

An LED lamp bulb, comprising: an LED lamp substrate () having at least one LED light source () mounted thereon; and an electrical isolation assembly () disposed on the LED lamp substrate (), wherein, the electrical isolation assembly () electrically isolates the LED lamp substrate's charged part from outside of the LED lamp substrate (). The LED lamp bulb can protect user from contacting the charged part inside the lamp housing () when the LED lamp bulb is broken and thereby avoid electric shock accidents. In addition, the directions of the light emitted by the LED light sources () can be changed to achieve different kinds of lighting effects.
