大型飞机模型是否会生锈主要取决于其制作材料。如果模型部分部件是金属材质，在一定条件下是会生锈的；如果是塑料、木质或复合材料等非金属材质的模型，则通常不会生锈。以下是金属材质飞机模型生锈的原因及处理方法：

Whether a large aircraft model will rust mainly depends on its manufacturing materials. If some parts of the model are made of metal, they will rust under certain conditions; If the model is made of non-metallic materials such as plastic, wood, or composite materials, it usually does not rust. The following are the reasons and treatment methods for rusting of metal aircraft models:

生锈原因

Reasons for rusting

材质因素：如果模型使用的金属材料本身防锈性能较差，如普通的铁制品，就容易生锈。而一些合金材质，如不锈钢、铝合金等，具有较好的防锈性能，但在某些特定环境下，也可能会出现腐蚀生锈的情况。

Material factor: If the metal material used in the model has poor rust prevention performance, such as ordinary iron products, it is easy to rust. Some alloy materials, such as stainless steel and aluminum alloy, have good anti rust properties, but corrosion and rusting may also occur in certain specific environments.

环境因素：湿度是导致金属模型生锈的重要因素之一。当空气中的相对湿度达到一定程度（一般认为相对湿度超过 60%）时，金属表面会形成一层薄薄的水膜，这层水膜会加速金属的氧化反应，从而导致生锈。此外，空气中的污染物，如二氧化硫、氯化物等，也会与金属发生化学反应，加速生锈过程。

Environmental factors: Humidity is one of the important factors that cause rusting of metal models. When the relative humidity in the air reaches a certain level (generally considered to be over 60%), a thin water film will form on the metal surface, which will accelerate the oxidation reaction of the metal, leading to rust. In addition, pollutants in the air, such as sulfur dioxide and chlorides, can also undergo chemical reactions with metals, accelerating the rusting process.

处理方法

轻度生锈

Mild rusting

物理打磨：可以使用柔软的砂纸或钢丝绒轻轻擦拭生锈部位，将锈迹打磨掉。在打磨时要注意力度，避免刮伤模型表面。对于一些细节部位，可以使用牙签或棉签蘸取少量除锈剂进行局部处理。

Physical polishing: You can use soft sandpaper or steel wool to gently wipe the rusted area and polish off the rust. When polishing, pay attention to the strength to avoid scratching the surface of the model. For some details, a toothpick or cotton swab dipped in a small amount of rust remover can be used for local treatment.

化学除锈：市面上有专门的金属除锈剂，将除锈剂喷在生锈部位，然后用干净的布擦拭干净。除锈后，要及时用清水冲洗干净，并擦干模型表面，防止除锈剂残留对模型造成进一步腐蚀。

Chemical rust removal: There are specialized metal rust removers available on the market. Spray the rust remover onto the rusted area and then wipe it clean with a clean cloth. After rust removal, it is necessary to rinse with clean water in a timely manner and dry the surface of the model to prevent further corrosion of the model caused by residual rust remover.

重度生锈

Severe rusting

专业修复：如果生锈情况比较严重，可能需要将模型送到专业的模型修复店进行处理。专业人员会根据模型的具体情况，采用更复杂的修复工艺，如电解除锈、化学镀等方法来去除锈迹，并对模型进行修复和保养。

Professional repair: If the rust is severe, it may be necessary to send the model to a professional model repair shop for processing. Professional personnel will use more complex repair processes, such as electrolytic rust removal and chemical plating, to remove rust and repair and maintain the model based on its specific situation.

重新涂装：在除锈完成后，为了防止模型再次生锈，可以对模型进行重新涂装。先对模型表面进行清洁和打磨，然后喷上底漆，待底漆干燥后，再喷上面漆。选择质量好、防锈性能强的油漆，可以有效延长模型的使用寿命。

Repainting: After rust removal is completed, to prevent the model from rusting again, it can be repainted. First, clean and polish the surface of the model, then spray the primer. After the primer dries, spray the topcoat. Choosing paint with good quality and strong rust resistance can effectively extend the service life of the model.

为了防止大型飞机模型生锈，在日常保养中，应尽量将模型放置在干燥、通风良好的环境中，避免阳光直射和潮湿的环境。也可以定期给模型涂抹一些防锈油或保护漆，增强其防锈能力

In order to prevent large aircraft models from rusting, during daily maintenance, the models should be placed in a dry, well ventilated environment as much as possible, avoiding direct sunlight and humid environments. You can also regularly apply some anti rust oil or protective paint to the model to enhance its anti rust ability
