Xylar 2
Xylar® 2 is the cornerstone of a generation of hard, cermet finishes that offers a tough, sacrificial barrier to corrosion and wear.
Xylar® 101 is a sealer/topcoat that enhances the corrosion resistance of Xylar® 2. It is a dense, clear film that fills any surface pores on Xylar® 2 and together they represent a breakthrough in coating technology - a thin-film barrier with extreme corrosion resistance.
Xylar® 201 is a dry-film lubricant with a friction coefficient of approximately 0.06. Used by itself, Xylar® 201 provides the slickest dry-lubricating surface available. As a topcoat with Xylar® 2, it provides both low friction and extreme wear resistance.
Xylar属性
化学腐蚀问题:化学品来自酸,盐,海水,光化合物,燃料和其他氧化剂的腐蚀每年毁坏数十亿美元的金属设备。泵叶轮,加工辊,枕块,支架和数千个其他部件被腐蚀物氧化成故障。有时候失效就像液压活塞表面上的一个凹坑一样简单,它会切割密封盖;在其他情况下,失败是全面的结构崩溃。
解决方案:Xylar®2和2/101是防腐蚀的基石。 Xylar®2是一种多孔陶瓷涂层,非常坚硬,就结构金属而言,它是化学牺牲材料。应用于黑色金属,铝或其他金属时,在基材受到侵蚀之前,腐蚀性介质会“被腐蚀”。 Xylar®101是一种封闭剂/面漆,可封闭Xylar®2的任何表面孔隙.1至1.5密耳(0.0254至0.0381 mm)的组合在ASTM B117盐雾测试中提供令人难以置信的4000多小时保护。
应用:Xylar®2可以提供300至400小时的盐雾保护,或者在用Xylar®101顶涂时可以保护约6000小时。推荐应用包括泵叶轮,涡轮叶片压缩机外壳,阀体,搅拌器,石化反应器部件,造纸机部件,排气烟囱,船用五金件,用于照片处理的设备或其他需要薄膜保护的部件 - 温度一直高达1,200°F / 650°C。
电偶腐蚀问题:当不同金属连接在一起时会发生电偶腐蚀,从而在它们之间形成导电路径。通常,紧固件等接触点周围会发生故障,并可能导致承载能力完全丧失。典型的例子是汽车车身与安装在门槛上的铝质踢脚板之间的结合;车体(钢)和踢脚板之间的金属对金属接触促进了两者的腐蚀。
解决方案:Xylar®2金属陶瓷涂层打破了不同金属部件之间的电气路径。它很难(8H),使用简单,而且它很薄(1到1.5密耳),所以不会影响大多数元件的公差。 Xylar®2(1200°F / 650°C)的高温稳定性使其非常适用于不同金属之间的电气耦合可能导致腐蚀的发动机应用。
应用:Xylar®2和2/101用于在发动机/发电机应用,悬挂式安装,气缸,电气控制,工业制动器和离合器,气泵,卷轴,材料处理设备,工业烤箱等中分离异种金属。管道系统,减速器,滚珠丝杠,调速器系统,电机外壳以及数百种其他应用 - 在环境温度或极端温度下。
磨损和侵蚀
磨损和侵蚀是由于配合表面的磨损,粗糙的颗粒或气穴现象而导致基体逐渐丧失。在旋转部件上,这会导致轴和轴承的不平衡和意外应力。在静态部件上,会导致力量损失和最终失败。
Xylar®2金属陶瓷涂层提供独特的硬屏障防止磨损。 Xylar®2本身可以防止粗泥浆,汽蚀,石头啄影或粉煤灰侵蚀。在需要释放研磨剂的地方,Xylar®2可以涂覆Xylar®201以形成具有无与伦比的释放性能的硬质基质薄膜。 Xylar®2用于研磨应用,例如炉膛滑道,风管,粮食处理设备以及众多车辆底部部件,这些部件常常出现磨损或石头啄形。 Xylar®2/201的组合优选用于部件互相磨损或部件被拖曳在磨蚀介质上的应用。
摩擦问题:当两个配合部件相互滑动时产生摩擦。即使在轻负载情况下,两个表面之间的动态接触也会引起微小凹凸(表面凸起)焊接在一起,然后剪切掉。此外,摩擦接触会产生热量 - 因此金属部件和流体润滑剂的性能可能受损。
解决方案:Xylar®2/201是一种非常坚硬的干膜润滑剂,摩擦系数为0.06。没有其他喷涂系统能够匹配其磨损特性或其温度稳定性(600°F / 315°C)。此外,由于这种涂层组合薄 - 薄至1密耳 - 它可以用于精确装配的部件,而不会干扰其公差。
应用:Xylar®2/201在轴承和磨损应用领域(例如动力螺丝,齿轮,压缩机转子,离合器执行器,滑块和阀门)的性能优于任何现有的干膜润滑涂层。在“粘滑”是一个问题的轻负载条件下,它也是一种极好的涂料。例子包括手刹组件,其中铝合金与铝滑动或不锈钢与不锈钢滑动。
Xylar Properties
Problems AdressedSolutionsApplication
- Chemical Corrosion
- Chemical Corrosion from acids, salts, sea water, photo compounds, fuels, and other oxidizing agents destroys literally billions of dollars of metal equipment each year. Pump impellers, process rolls, pillow blocks, brackets, and thousands of other parts are oxidized to failure by corrosives. Sometimes failure is as simple as a pit on the surface of a hydraulic piston that cuts a gland seal; in other cases, failure is total structural collapse.
Xylar® 2 and 2/101 are the building blocks to corrosion protection. Xylar® 2 is a porous ceramic coating that is extremely hard and, with respect to structural metals, is chemically sacrificial. Applied to ferrous, aluminum, or other metals, it is "sacri- ficed" to a corrosive medium before the substrate is attacked. Xylar® 101 is a sealer/topcoat that closes any surface pores of Xylar® 2. The 1 to 1.5 mil (0.0254 to 0.0381 mm) combination provides an incredible 4,000+ hours of protection in ASTM B117 salt fog tests.Xylar® 2 gives 300 to 400 hours of salt fog protection, or about 6,000 hours of protection when topcoated with Xylar® 101. Recommended applications include pump impellers, turbine blades compressor housings, valve bodies, agitators, petrochemical reactor parts, paper machine components, exhaust stacks, marine hardware, equipment used in photo processing, or other parts that need thin film protection - at temperatures all the way up to 1,200°F/650°C.
- Galvanic corrosion
- Galvanic corrosion occurs when dissimilar metals are joined so that there is an electrically conductive path between them. Usually, failure occurs around points of contact such as fasteners and can lead to total loss of load-carrying capability. The classic example is the union between auto- motive bodies and aluminum kick guards that are mounted on the door sills; metal-to-metal contact between the body (steel) and the kick panels promotes corrosion of both.
Xylar® 2 cermet coating breaks the electrical path between dissimilar metal parts. It is hard (8H), simple to apply, and because it is so thin (1 to 1.5 mils) it does not interfere with most component tolerances. The high temperature stability of Xylar® 2 (1,200°F/650°C) makes it ideal for engine applications where the electrical couple between dissimilar metals could result in corrosion.Xylar® 2 and 2/101 are used to separate dissim- ilar metals in engine/generator applications, sus- pension mounts, air cylinders, electrical controls, industrial brakes and clutches, air pumps, reels, materials-handling equipment, industrial ovens, tubing systems, gear reducers, ball screws, governor systems, motor housing, and literally hundreds of other applications - at ambient or extreme temperatures.
- Abrasion and Erosion
- Abrasion and Erosion are the gradual loss of a sub- strate due to wear from a mating surface, harsh particles, or cavitation. On rotating parts, this results in imbalance and unexpected stresses on shafts and bearings. On static parts, it results in loss of strength and eventual failure.
Xylar® 2 cermet coatings provide an extraordinari- ly hard barrier shield against abrasive wear. By itself, Xylar® 2 protects against coarse slurries, cavitation, stone pecking, or erosion from fly ash. Where release of abrasives is required, Xylar® 2 can be topcoated with Xylar® 201 to form a hard matrix film with unsurpassed release.Xylar® 2 is used in abrasive applications such as furnace chutes, air ducts, grain-handling equip- ment, and numerous vehicle-underbody compo- nents where abrasive wear or stone pecking is common. The combination of Xylar® 2/201 is pre- ferred for applications where parts wear against each other, or where parts are dragged over abrasive media.
- Friction
- Friction is produced when two mating parts slide over each other. Even under light loads, momen- tary contact between the two surfaces causes minute asperities (surface projections) to weld together, then shear away. Also, rubbing contact generates heat - so much so that properties of both the metal parts and fluid lubricants can be damaged.
Xylar® 2/201 is an extremely hard dry-film lubricant with a friction coefficient of 0.06. No other sprayable coating system can match its wear characteristics or its temperature stability (600°F/315°C). Also, because this combination of coatings is thin - as thin as 1 mil - it can be used on precisely fitted parts without interfering with their tolerances.Xylar® 2/201 performs better than any existing dry-film lubricating coating in bearing and wear applications such as power screws, gears, com- pressor rotors, clutch actuators, slides, and valves. It is also an excellent coating to use in lightly loaded conditions where "stick-slip" is a problem. Examples include handbrake compo- nents where aluminum slides against aluminum or stainless slides against stainless.
