  Laser cladding refers to a surface modification technique widely used in industrial applications such as rapid manufacturing, parts repair, surface coating, and innovative alloy development. It involves the feeding of a stream of metallic powder or wire into a melt pool that is generated by a laser beam as it scans across the target. Laser cladding can be used to increase corrosion resistance, wear resistance or impact performance of metallic components, using a method of applying a fully dense, metallurgically bonded and virtually pure coating. Laser cladding materials with different lasers have been used: high power diode laser (848 nm), Nd:Yag laser (1064 nm), CO2 laser (10.64 µm), and excimer laser (248 nm). It is quite different from traditional welding or fusion bonding as a means to permanently bind the metals together by means of high-energy laser beams. Instead, it is usually achieved by injecting two metallic materials through a cryogenic chamber and then pressing or...

  The term Trunnion Spherical Bearings is a type of bearing that is often referred to as a cone-shape bearing. A Trunnion cone-shaped bearing is just what it sounds like: a cone with three circular sections. Its shape is such that each of the three circular sections is exactly opposite to the others in terms of angular momentum. So each section of the cone-shaped bearing receives a rotation about an axis parallel to the surface of the bearing, while the other two remain stationary. The rotation is caused by a turning motion in the bearing. Spherical Bearings is a unique design of cast iron bearing that is widely used in a wide range of industries. They are known for their excellent mechanical properties, which include corrosion resistance, bearing stiffness, high thermal conductivity, toughness, and ductility. This is the main reason why they are extensively used in a wide variety of industries like aviation, automotive, mining, power generation, railway, and construction to name...

  A liquid ring vacuum pumps is an energy-efficient rotating positive displacement pump found in many industries, including paper and polymers businesses, diesel/diesel engines, medical equipment, petroleum refineries, textile mills, aerospace, and semiconductor processes. A liquid ring vacuum pump has a series of copper tubes filled with liquid ring material. When the ring is rotated by an electrical current, it pumps the liquid from one tube to another. This liquid is very similar to a vacuum cleaner as it only pumps the waste materials away from the pump itself. There are two types of liquid ring vacuum pumps : direct and indirect flow. A direct flow pump works by compressing a gas in a ring that is then fed into a compression stage. The ring's walls are made of a ring of metal containing holes that are punctured when the vacuum pump's impeller is turned by the moving fluid. This puncturing and expansion create a large amount of gas pressure behind the ring, which forces t...
