Compared with traditional magnetron sputtering monochromatic PVD technology, the dual-color PVD process is more complex and cumbersome, and more difficult to produce, but the appearance effect is good, and the surface hardness of both colors is above HV600. Traditional magnetron sputtering monochromatic PVD technology uses laser engraving or wear technology on areas that need to achieve other colors to achieve dual-color effects.
Let's learn about PVD coating machine the application scope and advantages and disadvantages of the technology!
The application scope of PVD coating machine technology is as follows.
1) Carbon steel, alloy steel, stainless steel and titanium alloy and other metal materials;
2) The surface hardness of metal materials must be at least HV170 or higher.
The advantages of PVD coating machines are:
Compared with the traditional magnetron sputtering monochromatic PVD technology, the two-color PVD process is more complex, the process is more cumbersome, and the production is difficult, but the appearance effect is good, and the surface hardness of the two colors is above HV600. Traditional magnetron sputtering monochromatic PVD technology uses laser engraving or abrasion technology measures based on the entire PVD monochromatic to achieve the color effect in areas that need to achieve other colors. The newly processed area can only show the original color of the metal, and the surface hardness is about HV600, which is the surface hardness of the metal itself. On the other hand, the surface hardness after PVD is above HV600.
The disadvantages of PVD coating machine technology are as follows.
1) The process is more complex than traditional monochromatic PVD, the process is more complex, and the production difficulty is high;
2) The production yield is as low as about 65~70%, and the production yield of traditional monochromatic PVD is generally 85~90%;
3) The Price is 50~60% higher than traditional monochromatic PVD;
4) Due to the influence of the process and process, the production limitations of two-color PVD are many, and the influence of product structure is large, while traditional monochromatic PVD is mainly based on modern coating equipment (uniform heating technology, temperature measurement technology, non-equilibrium sputtering technology, auxiliary anode technology, medium-frequency power supply, pulse technology).
So, what is the principle of the PVD coating machine? In addition, its classification: mechanical pump: also known as the fore pump, the mechanical pump is a widely used low-vacuum pump, using oil to maintain the sealing effect, using mechanical methods to continuously change the volume of the intake cavity in the pump, and the volume of the gas in the container being sucked expands continuously to obtain a vacuum.
I. Classification of mechanical pumps: There are many types of mechanical pumps, and the commonly used ones are four types: slide valve type (mainly used in large equipment), piston reciprocating type, vane type, and rotary type.
II. The machine pump starts working from the atmosphere, and its main parameters are the ultimate vacuum and pumping speed, which are important basis for the design and selection of the machine pump. A single-stage pump can evacuate the container from the atmosphere to an ultimate vacuum of 1.0*10-1PA, and a two-stage mechanical pump can evacuate the container from the atmosphere to 6.7*10-2 or even higher. The pumping speed refers to the volume of gas that can be discharged per unit time when the rotary pump operates at the rated speed, Sth=2nVs=2nfsL fs represents the cavity cross-sectional area at the end of suction, if the oil is too little to get the sealing effect, the pump will leak, too much oil will block the suction hole, unable to suck and discharge. Usually, 0.5 cm of oil level is enough.
III. Mechanical pumps are often used to remove dry air, but with excessive oxygen content, they cannot remove explosive and corrosive gases.
