济南铝板http://www.brujobike.com/模具在工作中除了要求具有足够高的强度和韧性外,其表面性能对模具的工作性能和使用寿命至关重要。济南铝板模具的表面处理技术,是通过表面涂覆、表面改性或复合处理技术,改变模具表面的形态、化学成分、组织结构和应力状态,以获得所需表面性能的系统工程。
In addition to requiring Jinan aluminum mold having a sufficiently high strength and toughness, the surface properties is essential in the performance and working life of the mold. Jinan aluminum mold surface treatment technology is through the surface coating, surface modification or composite processing technology to change the mold surface morphology, chemical composition, structure and stress state in order to obtain the desired surface properties of systems engineering.

济南铝板模具从表面处理的方式上,又可分为:化学方法、物理方法、物理化学方法和机械方法。虽然旨在提高模具表面性能的新处理技术不断涌现,但在模具制造中应用较多的主要是渗氮、渗碳和硬化膜沉积。渗氮工艺有气体渗氮、离子渗氮、液体渗氮等方式,每一种渗氮方式中,都有若干种渗氮技术,可以适应不同钢种不同工件的要求。由于渗氮技术可形成优良性能的表面,并且渗氮工艺与模具钢的淬火工艺有良好的协调性,同时渗氮温度低,渗氮后不需激烈冷却,模具的变形极小,因此模具的表面强化是采用渗氮技术较早,也是应用最广泛的。
Jinan aluminum mold from the surface treatment methods can be divided into: chemical methods, physical methods, physicochemical methods, and mechanical methods. Although aimed at improving the performance of the new mold surface treatment technologies are emerging, but more in the mold manufacturing applications is mainly nitriding, carburizing and hardening film deposition. Nitriding gas nitriding, ion nitriding, liquid nitriding, etc., each of nitriding way,

there are several kinds of nitriding technology can be adapted to different requirements of different kinds of steel workpiece. Due to the formation of surface nitriding technology with excellent performance, and nitriding process and

die steel quenching processes have good coordination, while nitriding temperature is low, after nitriding without intense cooling, mold deformation is very small, so the mold nitriding surface hardening technique is the use of older, is the most widely used.
  
济南铝板http://www.brujobike.com/模具渗碳的目的,主要是为了提高模具的整体强韧性,即模具的工作表面具有高的强度和耐磨性,由此引入的技术思路是,用较低级的材料,即通过渗碳淬火来代替较高级别的材料,从而降低制造成本。硬化膜沉积技术目前较成熟的是CVD、PVD。为了增加膜层工件表面的结合强度,现在发展了多种增强型CVD、PVD技术。目前的技术条件下,硬化膜沉积技术的成本较高,仍然只在一些精密、长寿命模具上应用,如果采用建立热处理中心的方式,则涂覆硬化膜的成本会大大降低,更多的模具如果采用这一技术,可以整体提高我国的模具制造水平。
Jinan aluminum mold carburizing main purpose is to improve the overall strength and toughness of the mold, that the working surface of the mold with high strength and wear resistance, thus introducing the technology idea is to use

lower-grade materials, namely, by infiltration quenching carbon material instead of a high level, thereby reducing manufacturing costs. Hardened film deposition technology is currently more mature CVD, PVD. In order to increase the

bonding strength of the film surface, and now the development of a variety of enhanced CVD, PVD technology. Under the current technical conditions, the higher the cost of the hardened film deposition technology, still in some precision,

long life mold applications only, if the heat build-centric approach, the cost of the coating hardened film will be greatly reduced, more die If this technology can improve the overall level of China's mold manufacturing.
