Porous substrate coating
The present disclosure relates to a method for manufacturing a porous substrate coating and to a mechanical component equipped with such a coating, the method comprising the steps of: providing a substrate (31) to be protected, the substrate (31) containing pores (34); providing a liquid suspension (15) containing at least a first powder (21) and a second powder (22), the D50 of the first powder (21) being strictly less than the D50 of the second powder (22) and the electrophoretic mobility of the first powder (21) being strictly higher than the electrophoretic mobility of the second powder (22); providing a direct current generator (12); placing a substrate (31) in the suspension (15) as a first electrode and connecting the substrate (31) to a first terminal of the generator (12); placing a second electrode (14) in the suspension (15) and connecting the second electrode (14) to a second terminal of the generator (12); and applying a continuous or pulsed voltage of at least 10 V between the two electrodes (31, 14) for at least 1 minute.
本公开涉及一种用于制造多孔基材涂层的方法，并且涉及一种配备有这种涂层的机械部件，该方法包括以下步骤：提供待保护的基材(31)，该基材(31)含有孔隙(34)；提供至少含有第一粉末(21)和第二粉末(22)的液体悬浮液(15)，该第一粉末(21)的D50严格小于所述第二粉末(22)的D50，并且该第一粉末(21)的电泳迁移率严格高于所述第二粉体(22)的电泳迁移率；提供直流发电机(12)；将基材(31)放置在悬浮液(15)中，作为第一电极，并且将基材(31)连接到发电机(12)的第一端子；将第二电极(14)放置在悬浮液(15)中，并且将第二电极(14)连接到发电机(12)的第二端子；以及在两个电极(31、14)之间施加至少10V的连续电压或脉冲电压至少1分钟。
