Ematal硬化涂层
简历封面word
铝及铝合金表面添入二氧化钛后变成坚硬密实的绝缘氧化铝层。
此表面处理是在一种特殊的电解溶液中，通过基底材料的阳极化表面转换来进行的。添加一定量的钛、锆，及其它复合物，在物体表面形成坚硬、耐磨损、抗腐蚀的氧化层。特殊添加剂的应用，使 Ematal 涂层具备及高的稳定性。
clever的比较级Ematal硬化涂层的特点是有极强的耐磨损, 减摩性能, 对恶劣的大气及化学环境有极强的防护能力。Ematal涂层还适合复杂形状的精密物体。因其涂层密薄且厚度均匀，可理想保持被处理部件的尺寸。
royalblue高防护特性：
对恶劣的大气及酸、碱、盐等使用环境进行有效防护。（详见附表。）
高表面硬度
根据所采用的合金，Ematal涂层使处理部件得到超过石英和黄玉的表面硬度。（莫氏硬度7：8）。
高耐磨损性

cosco是什么意思
Ematal涂层具备极高的耐磨特性，尽管是薄薄的一层，已不怕使用中的各种“磨练”。
高涂覆能力
boarderEmatal涂层还可在极难处理的表面上（如极窄的孔、螺纹）形成相同的厚度和特性。覆盖力强，无一遗漏。
涂覆是从抗电流最小的部位开始的，直到均匀涂覆整个部件。
高尺寸精度
采用其它涂覆方法（如硬铬镀敷），涂层厚度大，表面分布不均。 Ematal涂覆是可控制的，涂覆后表面的精度尺寸保持在约 +3μm 的容差范围内。
高减摩特性
如上釉一样的无隙表面，Ematal涂层在适当预处理的部件上具有极低的摩擦系数。

其它特性
色泽多样：根据合金的不同，Ematal涂层的颜色会在浅灰到褐灰之间变化。当硅含量很高时，颜色为
黑色。采用异质合金时，涂层会再次显示出合金的纹理。
Ematal涂层还是一种良好的绝热和绝缘体（击穿电压约为35-60V/m）。
合金的选择：
选择合适的合金对保持Ematal涂层的最佳特性非常重要。象其它电解阳极铝方法一样，基底材料构成涂层的骨架。用纯铝可达到最佳的涂层特性。其次是所有适合作阳极化处理的合金。
Ematal涂层和基底材料间的非溶性结合，彻底排除了涂层剥落任何可能性。
Ematal涂层可再上油漆，但最好在它们已完全成形后再上。由于其硬度很高，对工具磨损很厉害，建议涂覆后不要对其作机加工。
应用
适合于需高耐磨表面的工件：转子、轮盘、轴承法兰、齿轮机构、离合器、活塞、阀壳体、嵌齿轮、夹具、面板、螺钉等。
Ematal
Aluminum and aluminum alloy surface after the inrtion of titanium dioxide hard shot into the insulation layer of alumina.
This surface treatment in a special electrolytic solution, the substrate surface of the anode to the change. Add a certain amount of titanium, zirconium, and other complexes, the hard surface of objects, wear-resistant, corrosion-resistant layer of oxidation. Application of special additives, coatings have Ematal and high stability. .
Ematal hardening coating is characterized by a highly abrasion-resistance, friction reduction properties unfavorable atmospheric chemical environment and have a strong defen capability. Ematal coating also suitable for precision complex shape objects. Their cret thin coating thickness uniformity can be dealt with to maintain an ideal component size.
High protective characteristics
The bad air and acid, alkali and salt u of the environment for effective protection.
High surface hardness
According to the alloy coating Ematal processing components exceeding topaz and quartz on the su
rface hardness. (Mo's hardness 7:8).
High wear resistance
Ematal coating with high wear-resistant properties, albeit thin layer, which is not afraid to u the "tempering."

High Coated capacity
Ematal coating can also be extremely difficult to deal with the surface (such as a very narrow hole, the thread) formation and the thickness of the same characteristics. Strong coverage, no one omission. Coated resistance from the current minimum starting position, until evenly coated
components as a whole.
考试网站High dimensional accuracy
Coated using other methods (such as the hard chromium plating deposition), the coating thickness, surface uneven distribution. Ematal coating can be controlled by the surface coating of precision size remain at about +3 m tolerance limits.
High friction-reduction
If glaze for the same gap without surface coating Ematal appropriate pretreatment on the components is extremely low coefficient of friction.
Other characteristics :
Color diversity : According to the different alloys, Ematal coating in the color of light gray to brown ash between changes. When a high silicon content, color black. Heterogeneity using alloys, coating will once again demonstrates alloy texture. Ematal coating is a good insulation and insulator (about 35-60V/m breakdown voltage).
Alloy choice :
Choo a suitable alloy coating Ematal to maintain the best characteristics is very important. Like other aluminum anode electrolytic method, the substrate coating composition skeleton. Aluminum can be ud to achieve the best characteristics of the coating. Secondly, all suitable for the anode of the alloy. Ematal coating and the substrate with non-soluble, coating completely ruled out any possibility of falling off. Ematal coating can be painting, but the best in their future has taken shape o
n. Becau of its high hardness and wear very powerful tool, the propod coated not for its machining.

Application :
Suited to the need of high wear-resistant surface of the work piece : rotor, roulette, flange
bearings, gears, clutch, piston, valve shell, inlay gear, Fixture, panels, such as screws.
