Wear Resistance of Titanium Carbonitride Plate
Cermet hardness is higher than sintered carbide material, compared with hard alloy, in high temperature conditions and ferrous metal processed parts with low affinity, can obtain better surface finish, from low to high speed machining possible. High tool life during high speed finishing. Compared with the coating carbide, more suitable for light cutting (finishing). In the same cutting conditions, can be more wear resistance and surface accuracy.

The ceramic coating technology characteristics of ceramic coating technology compared with the overall structure of ceramic materials
The ceramic coating technology characteristics of ceramic coating technology compared with the overall structure of ceramic materials Ceramic coating technology features Compared with the overall structure of ceramic materials,ceramic coating technology has the following characteristics: 1. Can be organic to the strength of metal materials, easy processing and ceramic materials such as high temperature, wear and corrosion resistance and other characteristics together. In the case of 2. Reasonable choice of coating materials and the appropriate spraying process, you can get a variety of functional surface coating. In the case of 3. Restricted by the matrix: The base material for thermal spraying may be inorganic materials such as metal, ceramic, cement, refractory material, stone, gypsum and the like, or organic materials such as plastic, rubber, wood and paper. In the case of 4. Not subject to the size of the workpiece and the construction site. In the case of 5. Coating deposition rate is fast, the thickness is controllable, the craft is simple. 6. Ceramic coating of the workability is good, and the coating can be damaged after the spray. For more information please link: www.langfengmaterials.com,please contact us: sales@langfengmaterials.com
The impact of cutting temperature on the workpiece,tool and cutting process
The impact of cutting temperature on the workpiece,tool and cutting process High cutting temperature is the main reason for the tool wear, it will limit the productivity;Cutting temperature will reduce the machining precision,make the finished surface residual stress and other defects. (1) cutting temperature of the workpiece material strength and cutting force of the impact. Although the high temperature during cutting, but the impact of temperature on the workpiece material cutting hardness and strength is not great;shear stress area is not very obvious. (2) the influence of the cutting tool material. Suitably increase the cutting temperature,to improve the toughness of cemented carbide is advantageous. (3) Effect of the dimensional accuracy of the workpiece (4) the use of automatic temperature control cutting speed/cutting feed (5) the use of cutting temperature and cutting force control tool wear For more information please link: www.langfengmaterials.com,please contact us: sales@langfengmaterials.com
Large-scale steel structure thermal spraying long-term preservation
Due to its advantages of good mechanical properties, strong bearing capacity, easy manufacture, easy to adopt industrialized production, short construction and installation cycle and good sealing performance, the steel structure has been widely used in the national economy construction such as large-span structures (bridges, stadiums Roof truss, etc.), light steel structure (medium and large workshop), high-rise building (New York World Trade Center and Shanghai Jinmao Building, etc.), shell and shell structure (pressure vessel and long-distance pipeline). However, during service, the steel structure is prone to chemical, electrochemical or physical effects with the environment medium in which it is located, causing deterioration of the material and failure of the steel structure, which is often referred to as corrosion of the steel structure.
WEDM processing steps and requirements
According to the procedures after the production of a single tape, we must put the program and the production of a good tape one by one proofreading, with a good proof of the tape to the program after the controller can try to try the model, the simple grasp of the workpiece can be processed directly The On the size of the high precision, convex and concave mold with a small gap between the mold, we must use thin material test cut, engaged in cutting pieces can check its accuracy and with the gap. If you find that does not meet the requirements, should be timely analysis, identify the problem, modify the program until qualified before the formal processing of mold. This step is to avoid an important part of the workpiece scrap.
