Piston crank agitation mechanism for physical vapor deposition conformal coatings on powder

A device for deposition of conformal coatings, the device comprising:

• a powder container having a first side and a second side opposite and spaced apart from the first side, wherein the first side is configured to contain a powder;
• a connecting rod having a first end and a second end opposite and spaced apart from the first end, wherein the first end is directly hingedly coupled to the second side of the powder container;
• and
• a crankshaft having a crankshaft longitudinal axis, a main shaft portion extending along the crankshaft longitudinal axis, and a cam portion radially offset from and rotatable about the crankshaft longitudinal axis, wherein the second end of the connecting rod is directly rotatably coupled to the cam portion,
• wherein rotation of the crankshaft about the crankshaft longitudinal axis causes the second end of the connecting rod to rotate about the crankshaft longitudinal axis such that the connecting rod causes the powder container to linearly oscillate between a first position and a second position, wherein the powder container is closer in the first position than in the second position to the crankshaft longitudinal axis.
