Electromagnetic Pulse Cladding (EMPC) uses ultra-high transient magnetic fields ($B > 25\text{ T}$) generated by single-turn or multi-turn compression coils to accelerate a conductive flyer plate or tubular sleeve against a substrate at supersonic speeds ($V_p = 250 - 500\text{ m/s}$).
Key governing physical relationships include:
- Lorentz Magnetic Pressure: $$P_{\text{mag}} = \frac{B^2}{2 \mu_0}$$ where $\mu_0 = 4\pi \times 10^{-7}\text{ H/m}$. At 32 Tesla, $P_{\text{mag}} \approx 407.4\text{ MPa}$.
- Flyer Acceleration Velocity: $$V_p = \sqrt{\frac{2 P_{\text{mag}} h_0}{\rho \cdot t_f}}$$ derived from constant-force work-energy integration across stand-off clearance $h_0$.
- Collision Angle Requirement: Solid-state atomic bonding requires $\beta$ between $8^\circ$ and $22^\circ$ to create continuous interfacial plastic surface jetting that ejects native surface oxides without melting the bulk metals.
