Laser machining or stamping of nickel-titanium alloys (Nitinol) creates surface defects, like oxide layers, heat-affected zones (HAZ), and pulse marks. The expansion process turns these defects into potential sites of crack propagation.
MicroBlasting removes these defects, imparting a textured finish to the surface of the device. While a matte finish may seem contrary to the goal of electropolishing, this uniform finish speeds the polishing process. The more uniform the texture, the shinier the polish.
Nitinol requires a fine ceramic media like 17.5 µ aluminum oxide. The abrasive registers as a 9 on the Mohs scale of hardness which means that it effectively transfers energy to a brittle oxide layer and shatters it away quickly. Fortunately, the blocky shape of the aluminum oxide particles will not effectively cut into the ductile base material.
Due to volume and precision requirements, this application benefits from automation. Our Advanced Lathe and JetCenter platforms are able to follow the profile of a nitinol frame, ensuring uniform mass removal.
