Embodiment 2
[0040] A kind of ultrasonic vibration-electromagnetic stirring composite energy field assisted laser cladding method, it comprises the following steps:
[0041] (1) Use the preset method to pre-spread the required powder on the cladding substrate by means of binder or powder tableting, and place it in a vacuum drying oven to dry;
[0042] (2) Connect the dried cladding matrix with pre-set powder to the ultrasonic vibration device through a threaded rod, and place it horizontally at the center of the coaxial lines of the two excitation coils;
[0043] (3) Adjust the frequency and power of the ultrasonic power supply so that the cladding substrate with the pre-set powder produces an amplitude of 0.1-50 μm and a vibration frequency of 20-80 kHz. At the same time, the electronic voltage regulator is automatically adjusted to make the current in the circuit in the 3-20A is adjustable, and an alternating magnetic field of 9.7-65.7mT is generated in the cladding area;
