Abstract

The invention belongs to the technical field of spraying equipment, and discloses a cold spraying system and method. The cold spray system comprises a platform deck used for bearing workpieces, an adjustment mechanism rotationally connected to the platform deck, a spraying mechanism located on one side of the adjustment mechanism and a control mechanism, wherein the adjustment mechanism can adjustthe platform deck to move in the X direction, the Y direction and the Z direction and rotate in the X direction and the Y direction, and every two of the X direction, the Y direction and the Z direction are perpendicular to each other; the spraying mechanism can spray powder to the workpieces; and the control mechanism is electrically connected to the adjustment mechanism and the spraying mechanism. Through cooperation of the adjustment mechanism, the spraying mechanism and the control mechanism, the control mechanism controls the adjustment mechanism to do three-dimensional movement and two-dimensional rotation, and the spraying mechanism is adjusted in time to cooperate with the adjustment mechanism, so that the spraying mechanism can accurately spray the powder onto the workpieces, andthree-dimensional printing forming of the complex structure is achieved.

Description

technical field [0001] The invention relates to the technical field of spraying equipment, in particular to a cold spraying system and method. Background technique [0002] Supersonic cold spraying, also known as low-pressure cold spraying, is a 3D printing technology for metal spraying. Because the compressed gas can generate supersonic airflow through the zoom tube, the powder is sent into the supersonic airflow in the axial direction to form a gas-solid two-phase flow. After being accelerated, it hits the substrate in a completely solid state, and a large plastic deformation occurs and is deposited on the A coating is formed on the surface of the substrate. Cold spraying is used to prepare various functional coatings and nano-coatings, and has been widely used in automobile manufacturing, repair and remanufacturing of mechanical parts, aerospace and other fields. [0003] Since the existing spraying equipment cannot move with multiple degrees of freedom, for workpieces ...
