Abstract:

Sn, Zn, Al, Cu and brass were sprayed on glass plate with electrically operated pistol under various conditions, and the forms and sizes of their particles were examined from their microphotographs. The air pressure is an important factor affecting the size, that is, the size decreases considerably as the pressure rises. The spraying distance, the distance between the pistol and the articles to be coated, has also a great influence upon the size, while the arc voltage and the wire feeding speed has a very little. influence. From the form of each particle, it is deduced that the disintegration and the association of the particles occur during the transportation. And also, it was possible to observe the orientation of the particles along the track of coating.
