For tribo spray, it should be tested before commencing production.Application settings Fluidizing air pressure: 1.5kg/cm2 initially then 1kg/cm2Transport air pressure: 0.5 to 0.8 kg/cmRecommended voltage: 65 to 70kVCuring limits Primer should be cured using the recommended curingschedules, before application of the topcoat. The objecttemperature must not be below 110°C or above 220°C.Recommended DFT 60-120 µmRecycling Trials, with suitable recycling equipment, must be carriedout before commencing production. Attention should bepaid to the ratio of new powder, a minimum of 80% mustbe used. Gun nozzles must be cleaned every 30 minutes.Note: Failure to comply with the recommended curing conditions may affect the adhesion ofthe topcoat and cause performance degradation. Parts coated with Interpon RDX PZ shouldnot be handled if possible. If unavoidable, clean lint-free gloves must be worn.Curing Interpon RDX PZ shows a wide curing range must allowing application on substrates of different nature and thicknesses.Green curing Full semi-curingObject temperature Min Max Min Max110°C 15’ 40’130°C 12’ 30’160°C 12’ 23’170°C 8’ 17’180°C 6’13’200°C 2’ 8’220°C 1’30’’ 5’30’’The Interpon RDX PZ system provides excellent protection against corrosion on the surface to which it is applied. However, the efficiency of this protection depends on the surface, its preparation before coating and the topcoat applied.If there is penetrating damage through the coating system to the substrate, there may be localized signs of corrosion where damage has occurred but this will not affect the adhesion of the film to the adjacent surface. Interpon RDX PZ considerably limits the extent of spread of corrosion in the event of coating damage.Topcoat Application Primer should be over-coated on the same site within 12 hours of applying the primer. If the delay exceeds 12 hours the parts should be heated for 12 minutes at 160°C. (object temperature). The delay must not exceed 24 hours.Refer to the Product Data Sheet for the powder topcoat for application parameters.To ensure the integrity of the system, as well as optimum performance, the whole system must be cured in accordance with the recommended curing conditions for the topcoat. Curing should be carried out in a convection oven, optionally with infra-red heaters. There must be a uniform heat distribution inside the oven.Note: Failure to comply with the recommended final curing conditions may cause variations in color and gloss and cause performance degradation of the system. A detailed protocol for applying Interpon RDX PZ system is available on request.Damage repair Any damage of the Interpon RDX PZ coating system must be repaired as soon as possible.Surface preparationDamaged areas must be clean and free of grease or rust. Dry-sand the area with 600grade paper down to the substrate. The area must be completely free of dust and cleanedwith a non-aggressive solvent before proceeding.ApplicationFor repairs the following two-coat liquid paint system from International Protective Coatingsis recommended:1st Coat: two-pack zinc-rich epoxy primer, Interzinc 722nd Coat: two-pack polyurethane topcoat, Interthane 990Safety Precautions This product is intended for use only by professional applicators in industrial environments and should not be used without reference to the relevant health and safety data sheetwhich Akzo Nobel has provided to its customers.Disclaimer IMPORTANT NOTE: The information in this data sheet is not intended to be exhaustive and is based on the present state of our knowledge and on current laws: any person using the product for any purpose other than that specificallyrecommended in the technical data sheet without first obtaining written confirmation from us as to the suitability ofthe product for the intended purpose does so at his own risk.

粉末冶金工艺的基本工序(三篇)
粉末冶金工艺的基本工序1、原料粉末的制备。
现有的制粉方法大体可分为两类：机械法和物理化学法。
而机械法可分为：机械粉碎及雾化法;物理化学法又分为：电化腐蚀法、还原法、化合法、还原-化合法、气相沉积法、液相沉积法以及电解法。
其中应用最为广泛的是还原法、雾化法和电解法。
2、粉末成型为所需形状的坯块。
成型的目的是制得一定形状和尺寸的压坯，并使其具有一定的密度和强度。
成型的方法基本上分为加压成型和无压成型。
加压成型中应用最多的是模压成型。
3、坯块的烧结。
烧结是粉末冶金工艺中的关键性工序。
成型后的压坯通过烧结使其得到所要求的最终物理机械性能。
烧结又分为单元系烧结和多元系烧结。
对于单元系和多元系的固相烧结，烧结温度比所用的金属及合金的熔点低;对于多元系的液相烧结，烧结温度一般比其中难熔成分的熔点低，而高于易熔成分的熔点。
除普通烧结外，还有松装烧结、熔浸法、热压法等特殊的烧结工艺。
4、产品的后序处理。
烧结后的处理，可以根据产品要求的不同，采取多种方式。
如精整、浸油、机加工、热处理及电镀。
此外，近年来一些新工艺如轧制、锻造也应用于粉末冶金材料烧结后的加工，取得较理想的效果。
粉末冶金工艺的基本工序（二）粉末冶金是一种利用粉末作为原料，通过压制、成型、烧结等工艺制备制品的工艺方法。
它具有高效率、高精度和可靠性好等特点，广泛应用于各个领域，包括汽车、航空航天、电子等。
粉末冶金工艺的基本工序包括粉末选料、混合、成型、烧结等。
首先是粉末选料。
粉末冶金工艺中所用的粉末要求颗粒细小、纯度高、形状均匀。
常见的粉末材料包括金属、陶瓷和合金等。
粉末选料的过程中需要考虑到材料的物理化学性质，并进行相应的测试和分析。
接下来是粉末的混合。
混合是将不同种类的粉末按一定比例混合在一起，以获得所需的材料性能。
混合可以通过机械混合、化学方法和物理方法等进行。
在混合过程中，需要控制混合时间和混合速度，以保证混合的均匀性。
然后是成型。
成型是将混合好的粉末放入模具中进行压制或注塑成型。
粉末冶金工艺基本知识
粉末冶金工艺基本知识粉末冶金成形粉末冶金工艺及材料粉末冶金是制取金属粉末并通过成形和烧结等工艺将金属粉末或与非金属粉末的混合物制成制品的加工方法，既可制取用普通熔炼方法难以制取的特殊材料，又可制造各种精密的机械零件，省工省料。
但其模具和金属粉末成本较高，批量小或制品尺寸过大时不宜采用。
粉末冶金材料和工艺与传统材料工艺相比，具有以下特点：1．粉末冶金工艺是在低于基体金属的熔点下进行的，因此可以获得熔点、密度相差悬殊的多种金属、金属与陶瓷、金属与塑料等多相不均质的特殊功能复合材料和制品。
2．提高材料性能。
用特殊方法制取的细小金属或合金粉末，凝固速度极快、晶粒细小均匀，保证了材料的组织均匀，性能稳定，以及良好的冷、热加工性能，且粉末颗粒不受合金元素和含量的限制，可提高强化相含量，从而发展新的材料体系。
3．利用各种成形工艺，可以将粉末原料直接成形为少余量、无余量的毛坯或净形零件，大量减少机加工量。
提高材料利用率，降低成本。
粉末冶金的品种繁多，主要有：钨等难熔金属及合金制品；用Co、Ni等作粘结剂的碳化钨（WC）、碳化钛（TiC）、碳化钽（TaC）等硬质合金，用于制造切削刀具和耐磨刀具中的钻头、车刀、铣刀，还可制造模具等；Cu合金、不锈钢及Ni等多孔材料，用于制造烧结含油轴承、烧结金属过滤器及纺织环等。
随着粉末冶金生产技术的发展，粉末冶金及其制品将在更加广泛的应用。
1 粉末冶金基础知识⒈1 粉末的化学成分及性能尺寸小于1mm的离散颗粒的集合体通常称为粉末，其计量单位一般是以微米（μm）或纳米（nm）。
1.粉末的化学成分常用的金属粉末有铁、铜、铝等及其合金的粉末，要求其杂质和气体含量不超过1%～2%，否则会影响制品的质量。
2.粉末的物理性能⑴粒度及粒度分布粉料中能分开并独立存在的最小实体为单颗粒。
实际的粉末往往是团聚了的颗粒，即二次颗粒。
图7.1.1描绘了由若干一次颗粒聚集成二次颗粒的情形。
实际的粉末颗粒体中不同尺寸所占的百分比即为粒度分布。
