徐州INA軸承BK0810A表層強化需要用到的處理方式

發布時間:2019-01-16 05:21:18        

進口徐州INA軸承零件的工作表面和核心在狀態、結構和性能要求上差別很大,但整體熱處理往往使其難以考慮,材料的潛力無法充分發揮。

The working surface and core of the imported Xuzhou INA bearing parts differ greatly in the state, structure and performance requirements, but the overall heat treatment often makes it difficult to c***ider, and the potential of the material can not be fully exploited.

目前,表面強化技術可分為五類:表面變形強化、表面熱處理強化、化學熱處理強化、表面冶金強化和表面薄膜強化。

At present, surface strengthening technology can be divided into five categories: surface deformation strengthening, surface heat treatment strengthening, chemical heat treatment strengthening, surface metallurgical strengthening and surface film strengthening.

1?;瘜W熱處理強化

1. Chemical heat treatment strengthening

金屬表面的化學成分可以通過某些元素的固體擴散和滲*透來改變,從而實現徐州INA軸承表面強化。這種方法稱為化學熱處理強化,也稱為擴散熱處理。進口軸承鋼的滲碳工藝和進口軸承套的滾針滲氮強化處理屬于這種強化方法。

The chemical composition of metal surface can be changed by solid diffusion and infiltration of some elements, so that the surface strengthening of Xuzhou INA bearing can be realized. This method is called chemical heat treatment strengthening, also known as diffusion heat treatment. The carburizing process of imported bearing steel and the needle nitriding strengthening treatment of imported bearing sleeve belong to this strengthening method.

2。表面變形強化

2. Surface Deformation Strengthening

金屬表面采用機械方法塑性變形,形成高硬度、高*強度的硬化層。這種徐州INA軸承表面強化方法稱為表面變形強化,又稱加工硬化。這些方法主要應用于進口軸承行業:滾動體表面沖擊強化就是這些方法的應用。精*密軋制已成為環件強化的一種新方法。

The metal surface is plastic deformed by mechanical method to form a hardened layer with high hardness and strength. The surface strengthening method of Xuzhou INA bearing is called surface deformation strengthening, also known as work hardening. These methods are mainly used in the imported bearing industry: the impact strengthening of rolling surface is the application of these methods. Precision-dense rolling has become a new method of ring strengthening.

3。表面熱處理強化

3. Surface heat treatment strengthening

在大多數情況下,軸承疲勞損傷會導致軸承疲勞損傷。一般來說,軸承疲勞損傷造成的損傷只有三分之一來自潤滑不順暢,三分之一來自污染物進入軸承或安裝和處理不當。該方法對提高大型和特大型徐州INA軸承零件在一定沖擊載荷下的耐磨性和疲勞強度特別有*效。

In most cases, bearing fatigue damage will lead to bearing fatigue damage. Generally speaking, only one third of the damage caused by bearing fatigue damage comes from poor lubrication, and one third comes from the incorrect entry of pollutants into the bearing or the improper installation and treatment. This method is especially effective for improving the wear resistance and fatigue strength of large and super-large Xuzhou INA bearing parts under certain impact loads.

4。表面冶金:從礦石中提取金屬或金屬化合物進行強化。

4. Surface metallurgy: extraction of metals or metal compounds from ores for strengthening.

它的特點是加熱快,熱度密度高,熔化金屬表面或金屬表面合金,然后冷凝凝固,以獲得特殊的結構或強化層特征。

It is characterized by fast heating, high heat density, melting metal surface or metal surface alloys, and then condensation to obtain special structure or strengthening layer characteristics.

5。表面薄膜強化

5. Surface film strengthening

物理和化學方法被用來覆蓋具有不同基體性質的金屬表面,稱為表面薄膜強化。當識別徐州INA軸承的真實性時,通過觸摸軸承上的鋼印來識別軸承的真實性是更快、更準確的。這枚***用手觸摸是不可觸摸的,但用釘子輕輕觸摸是可以感覺到的。

Physical and chemical methods are used to cover metal surfaces with different matrix properties, called surface film strengthening. When identifying the authenticity of Xuzhou INA bearing, it is faster and more accurate to identify the authenticity of bearing by touching the steel stamp on the bearing. The stamp is not touchable by hand, but it can be felt by touching it lightly with a nail.
