进口徐州INA轴承零件的工作表面和核心在状态、结构和性能要求上差别很大，但整体热处理往往使其难以考虑，材料的潜力无法充分发挥。

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，表面强化技术可分为五类：表面变形强化、表面热处理强化、化学热处理强化、表面冶金强化和表面薄膜强化。

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。化学热处理强化

1. Chemical heat treatment strengthening

金属表面的化学成分可以通过某些元素的固体扩散和渗*透来改变，从而实现徐州INA轴承表面强化。这种方法称为化学热处理强化，也称为扩散热处理。进口轴承钢的渗碳工艺和进口轴承套的滚针渗氮强化处理属于这种强化方法。

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。表面变形强化

2. Surface Deformation Strengthening

金属表面采用机械方法塑性变形，形成高硬度、高*强度的硬化层。这种徐州INA轴承表面强化方法称为表面变形强化，又称加工硬化。这些方法主要应用于进口轴承行业：滚动体表面冲击强化就是这些方法的应用。精*密轧制已成为环件强化的一种新方法。

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。表面热处理强化

3. Surface heat treatment strengthening

在大多数情况下，轴承疲劳损伤会导致轴承疲劳损伤。一般来说，轴承疲劳损伤造成的损伤只有三分之一来自润滑不顺畅，三分之一来自污染物进入轴承或安装和处理不当。该方法对提高大型和特大型徐州INA轴承零件在一定冲击载荷下的耐磨性和疲劳强度特别有*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：从矿石中提取金属或金属化合物进行强化。

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

它的特点是加热快，热度密度高，熔化金属表面或金属表面合金，然后冷凝凝固，以获得特殊的结构或强化层特征。

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。表面薄膜强化

5. Surface film strengthening

物理和化学方法被用来覆盖具有不同基体性质的金属表面，称为表面薄膜强化。当识别徐州INA轴承的真实性时，通过触摸轴承上的钢印来识别轴承的真实性是更快、更准确的。这枚***用手触摸是不可触摸的，但用钉子轻轻触摸是可以感觉到的。

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.
