English to Chinese Tech/Engineering Engineering (general)

Context:

By controlling the depositional thickness, the weight of the metal added to the microparticulate does not weigh down the misarticulate, thereby leaving it capable of remaining airborne for a certain period of time.

是一个材料表面处理的专利。用物理方法（沉积）让颗粒材料表面金属化，因为不知 misarticulate 做何解，整句也就不清楚了。
