To form a common alloying method is not readily available compounds, and metastable phase and the new phase, but also in the surface alloys with special properties together elements consumption low Qian case. This alloy layer due to some performance above the substrate, so we reached the table while the purpose of the modification. The most prominent feature of the laser surface alloying process is only in the melting zone and a small impact area occurred changes in the composition, microstructure and properties, the thermal effect of the matrix can be reduced to a minimum, the deformation caused minimal. That it can meet the surface of the need to use, without sacrificing the overall characteristics of the structure. The alloying elements are completely dissolved in the surface. green laser pointer will be safer for the human body and the environment. Can also prepare traditional metallurgical methods can not get some special materials, such as superconducting alloy, the surface of metal, glass, etc.. Compared with the ordinary arc surface hardening and plasma spraying, laser alloying has the following advantages. The laser radiation energy is highly concentrated, can be transported over long distances through the air. Is a fast approach, the efficient use of energy. Power density can be accurately controlled and the heating rate and thus a small deformation, while the arc hardening, plasma spraying is the uneven heating and cooling, thermal shock in the quenching process, resulting in cross-shaped and cracking, it often requires straightening and grinding processing. Triple-color animationgreen laser pointer will be introduced.
Such high-power spindle motor characteristics generally can be divided into brushless frequency high-speed AC motor and brush AC motor, the main difference is: high speed brushless frequency conversion motor, variable speed range of 70.06 million rev / min, and the general brush exchange maximum speed of the motor is not ultra-24000 rev / min: high precision brushless frequency conversion motor rotation, wear, low noise, make noise significantly lower than the brush AC motor; brushless frequency conversion motor stall characteristics, due to the inverter special limiting circuit, short-term stall not burned the motor control mode and speed options: control methods can be divided into three: all the computing work to complete computer-controlled engraving machine computer is at work other layout work, such waste may be solid computer misuse. Here will introduce the difference between the industrial level and toy level of green laser pointer.
The correct method of installation accessories. Data lines: parallel port connection to computer (two rows of fine needle-shaped), the other end to connect the machine output (in the right side of the machine front). Pump: the pump outlet received the machine aqueduct (length catheter), and then pump into the water (pump water work, short catheter water to form a loop cycle), plug in the pump power in front of the machine work, so that The water to be recycled in order to reduce the temperature of the laser tube. Exhaust: exhaust fan inserted in the exhaust port of the machine at the other end on the outside in order to discharge the flue. What other difference do red laser beam and green laser beam of green laser pointer have besides the color?
