In the long focusing direction, the narrow sound beam and the annular illumination beam are coupled to form a photoacoustic coplanar mode, which improves the signal to noise ratio of the photoacoustic signal. The pattern of 360◦ circular laser radiation provides uniform illumination at all angles...
In a recent study, IN718 was mixed with a low melting point Ni-based braze alloy powder (MAR-M 002) to form a composite coating via a high-pressure cold spray process. The following heat treatment at a temperature near the liquidus temperature of the braze alloy enhanced the chemical ...
