The invention relates to a method for depositing an anti-corrosion coating on at least some of the surfaces of a metal substrate having at least one cavity with a diameter of emm < 2 mm and a length/width ratio higher than 150, using an aqueous solution containing powder of the metal to be deposited on the substrate, associated with an agent for protecting the surface of the metal powder, a diluent, and at least one additive, the particules of the suspension each having a diameter of d where d <= emm/10. 本发明涉及一种在金属基材的至少一部分表面上沉积防腐蚀涂层的方法，所述表面具有至少一个等量直径e<2mm并且长度/宽度比率大于150的空隙，其中使用含有要沉积于基材上的金属粉末和用于保护金属粉末表面的试剂、稀释剂以及至少一种添加剂的含水悬浮液，所述悬浮液的粒子各自具有的等量直径d使得d≤e/10。
