The surface treatment technology of the briquetting machine mold L.
Surface treatment technology of the briquetting machine mold In addition to the reasonable cooperation of the base body with high strength and toughness, the surface performance of the briquetting machine mold is essential to the working performance and service life of the mold. These surface properties are: abrasion resistance, corrosion resistance, friction coefficient, fatigue properties, and the like. These performance improvements, which rely solely on the improvement and improvement of the matrix material, are very limited and uneconomical, and surface treatment techniques can often achieve twice the result with half the effort, which is why surface treatment technology has developed rapidly. The surface treatment technology of the mold is to systematically change the morphology, chemical composition, microstructure and stress state of the mold surface by surface coating, surface modification or composite treatment technology to obtain the desired surface properties. From the way of surface treatment, it can be divided into: chemical methods, physical methods, physical and chemical methods, and mechanical methods. Although new treatment technologies are being developed to improve the surface properties of molds, more major nitriding, carburizing and hardening film deposits are used in mold manufacturing. 5. The nitriding process includes gas nitriding, ion nitriding, liquid nitriding, etc. In each type of nitriding method, there are several kinds of nitriding techniques, which can adapt to the requirements of different workpieces of different steel types. Because the nitriding technology can form a surface with excellent performance, and the nitriding process is well coordinated with the quenching process of the die steel, and the nitriding temperature does not require intense cooling after low nitriding, the deformation of the mold is extremely small, so the surface strengthening of the mold The use of nitriding technology is earlier and the most widely used. The purpose of mold carburizing is mainly to improve the overall strength and toughness of the mold, that is, the working surface of the mold has high strength and wear resistance. The technical idea introduced here is to reduce the manufacturing costs by replacing the higher-grade materials with lower-grade materials, ie by carburizing and quenching.
The most mature sclerosing film deposition technology is CVD and PVD. In order to increase the bonding strength of the surface of the film workpiece, various enhanced CVD, 'PVI) technologies have been developed. The hardened film deposition technology was first applied to tools (tools, cutting tools, measuring tools, etc.), and the results were excellent. A variety of tools have been used as a standard process for coating hardened films. Molds have been coated with hardened film technology since the 1980s. Under the current technical conditions, the cost of hardened film deposition technology (mainly equipment) is still high, and it is still only applied to some precision and long-life molds. If the method of establishing a heat treatment center is adopted, the cost of coating the cured film will be greatly reduced. If more molds adopt this technology, they can improve the overall level of mold manufacturing in China.

Bulletproof glass compositions vary but most common are laminated structures manufactured from several layers of glass bonded together with tough polyvinyl butyral (PVB) interlayer's.The performance requirements govern the number, and thickness of individual glass layers, thus affecting the overall thickness and weight.On impact the front layers of glass are designed to absorb the bullets initial impact energy by shattering allowing the subsequent glass layers and PVB to absorb the lower level shock waves.
