چکیده
In this work, two advanced technologies were applied for manufacturing a bimorph wavefront corrector: laser ablation, to vaporize conductive silver coating from piezoceramic surface, and parallel-gap resistance microwelding, provide reliable electrical contact between the piezodisk surface electrodes copper wires. A step-by-step guide mirror production is presented, together with ‘bottlenecks’. Optimization of ablation technique was carried out using an Nd:YAG output power 4 W frequency 20 kHz. comparison ultrasonic welding microwelding methods performed. The tensile strength in first case range 0.2…0.25 N system ‘copper wire–silver coating’. use made it possible increase value parameter same pair by almost times (0.45…0.5 N).

متن کاملA state-of-the-art review of mechanical rock excavation technologies
The first step in mining activities is rock excavation in both mine development and production. Constant pressure for cost reduction and creating an improved/safe work environment for personnel has naturally resulted in increased use of mechanical excavation systems in many mining operations. Also, mechanical excavation and mining is more compatible with automation, meaning possibility of reduc...

متن کاملDesign of defect spins in piezoelectric aluminum nitride for solid-state hybrid quantum technologies.
Spin defects in wide-band gap semiconductors are promising systems for the realization of quantum bits, or qubits, in solid-state environments. To date, defect qubits have only been realized in materials with strong covalent bonds. Here, we introduce a strain-driven scheme to rationally design defect spins in functional ionic crystals, which may operate as potential qubits. In particular, using...
