PVD (physical vapor deposition) coating is a type of Surface Treatment that is used to improve the performance of metal parts, by applying a thin layer of material onto the substrate through a vacuum chamber. This process provides a range of benefits, including increased hardness, improved wear resistance, and enhanced corrosion resistance.
PVD coatings are typically applied to metals such as stainless steel, titanium, and aluminum. They are particularly useful in applications where the substrate is subjected to high wear and tear, as the coatings help to reduce friction and limit the damage caused by abrasion. They are also used in the automotive industry to provide an aesthetic and functional finish to exterior parts.
PVD coatings can be tailored to meet specific application requirements, with a range of coating materials available, including titanium, chromium, and zirconium. These coatings can be deposited in a range of colors, such as black, gold, and silver, giving designers and manufacturers the flexibility to create parts with the desired appearance.
Another key benefit of PVD coating is its durability. The thin layer of coating can offer a long-lasting, high-performance finish, even in harsh or corrosive environments. This makes them particularly useful in outdoor applications, and in settings such as aerospace and medical devices, where reliability and durability are critical.
PVD coating is applied through a series of steps, including cleaning and pre-treatment of the substrate, coating material deposition, and post-treatment, such as polishing or annealing. The result is a thin, uniform layer of coating that provides a range of functional and aesthetic benefits.
In conclusion, PVD coating is a versatile and effective surface treatment for metal parts. It offers a range of benefits, including improved hardness, wear resistance, and corrosion resistance, as well as aesthetic options. By enhancing the performance and durability of metal parts, PVD coating plays an important role in improving the reliability and efficiency of a range of industries and applications.
How is the price of plate rubber bearing calculated
The rectangular volume accounting quotation of the price of 200 × 42 plate rubber bearing is the width and height price multiplied by the commodity price, but the conversion must be noted in the accounting process, we usually notify the customer should be millimeters, centimeters, of course, also in cubic centimeters Accounting prices, for example. The price of 300 × 42 × 20 is the price of 200 × 4.2 × 30, which is the price of the commodity. The support price accounting circle is a round area, made by the high R- * H formula, which is not given in the rubber support, such as the edge.
The plate rubber support is formed by bonding a layer of polytetrafluoroethylene with a thickness of 1.5-3mm to the common plate rubber support. In addition to the vertical rigidity and elastic deformation of ordinary plate rubber bearings, it can withstand vertical loads and adapt to the beam end rotation. The surface of the support cushion stone should be flat, clean, dry and free of floating sand. The elevation of the top surface of the support cushion stone is accurate. In the case of a flat slope, the support cushion stones at both ends of the same beam, the same bridge piers and the support cushion stones on the platform should be in the same design elevation plane, the relative height difference should not exceed ± 1.5 mm, and the height difference of the same support cushion stone should be less than 0.5 mm.
Plate rubber bearings are widely used in bridge construction, house earthquake resistance and other facilities. Before casting the beam body, place a support steel plate slightly larger than the support plane on the support. Weld anchor steel bars on the steel plate to connect with the beam body, and cast the support steel plate as part of the casting beam template. Make the bearing closely adhere to the top surface of the bottom steel plate and cushion stone.
The plate type rubber bearing is a general rubber bearing product formed by multi-layer thin steel plates and multi-layer rubber sheets of bridge rubber bearing. The product has satisfactory vertical rigidity and can support the upper structure of the bearing. The reaction force of the bridge can be transferred to the abutment by the rubber bearing of the bridge. The bearing has outstanding properties to deal with the rolling plate rubber bearing at the beam end of the bridge. There are two types of rectangular and circular, and other shapes. 200 × 42 plate rubber bearing price When a beam needs two or four bearings, a layer of cement mortar can be laid between the supporting cushion stone and the bearing to make it automatically level. At the same time, it can absorb some vibrations, translational motion, reduce the impact of live load on the bridge structure and pier, and extend the life of the bridge. Therefore, plate rubber bearings are widely used in highway and bridge engineering.
Plate rubber bearing function: It has satisfactory vertical stiffness to accept straight load, has outstanding performance, is used to rolling bridge rubber bearing at the beam end, and has large shear deformation to satisfy the horizontal displacement of the superstructure.
Features of plate rubber bearing: This product has been widely used in bridge construction, hydropower engineering, and seismic equipment for houses. Compared with the original steel bearing, the rubber bearing of the bridge has a simple structure, convenient installation, save steel, and low price. The maintenance is simple, easy to replace the same strength, and the low height of this product is beneficial to the design of the bridge bridge rubber bearing beam and to reduce the cost; it has excellent isolation effect, which can reduce the impact of live load and seismic force on the building. Design standards for reinforced concrete and prestressed concrete bridges (JTG D62 rubber bearings-2004 highway).
