The invention discloses a method for preparing a medical porous titanium or titanium alloy material coated with a tantalum coating on the surface. The method first adopts a 3D printing method to prepare a porous titanium skeleton or a porous titanium alloy skeleton, and then makes the porous titanium skeleton or porous titanium alloy After the skeleton is corroded, it is cleaned and dried, and then completely embedded in the ultrafine tantalum powder in the metal sheath, vacuum-sealed and then subjected to low-temperature diffusion sintering. Finally, the powder is removed after taking it out, and the medical porous titanium coated with tantalum coating is obtained. or titanium alloy material. The present invention coats tantalum on the surface of porous titanium skeleton or porous titanium alloy skeleton through powder embedding and low-temperature diffusion sintering to form a metallurgical bond, which greatly improves the bonding force between tantalum and the surface of porous titanium skeleton or porous titanium alloy skeleton, and solves the problem of The problem of poor bonding between the tantalum coating and the substrate overcomes the shortcomings of high cost and complicated procedures of the existing preparation methods.

The invention discloses a transition layer for a CIGS-based film photovoltaic cell and a preparation method of the transition layer. The preparation method comprises the steps of: providing a soda-lime glass substrate, forming a transition layer covering the surface of the soda-lime glass substrate, forming a molybdenum layer covering the transition layer, forming a light absorbing layer having a copper pyrite structure and covering the molybdenum layer, forming a buffer layer covering the light absorbing layer, and forming a window layer covering the buffer layer. According to the invention, the transition layer is deposited on the surface of the glass substrate, thus the adhesion problem between a molybdenum electrode layer and the glass substrate can be efficiently solved, and sodium materials can be prevented from uncontrollably diffusing into the light absorbing layer.

The invention relates to a thin film sintering electromagnetic wire induction heating bonding system and a method for manufacturing an electromagnetic wire. The system comprises a paying-off rack, a straightening device, a polishing machine, a water scrubbing device, an air drying device, a lapping device, a crawler, an induction heating device, a rolling device, an oven, a water-cooling blow-drying device and a take-up machine. Both the induction heating device and the rolling device can move back and forth. Because the induction heating device and the rolling device can move back and forth, when shutdown occurs to equipment, a thin film, namely a thin film located between a pressing device and the induction device, heated by the induction heating device can also be rolled by the rolling device to be tightly attached to a conductor, and therefore the problem that the thin film located between the pressing device and the induction device cannot be firmly bonded each time shutdown occurs to the equipment is solved; operation is simple and convenient, production efficiency is improved, and quality of products is stable.
