A coated reinforced tungsten alloy dart barrel features physical/chemical vapor deposition forming diamond-like carbon or titanium nitride thin film, providing low-friction protection and long-life surface. Tungsten alloy hardness ensures film adhesion, binder phase surface bonding blocking peeling. In grip, coating smooth fits fingertip, pressure smooth distribution, suitable light-touch low-resistance grip, wrist tension minimal. During throw, low shear guides sliding, release slippery no sticking, flight drag minimal suitable rapid successive. Processing vacuum chamber multi-layer deposition, substrate ion cleaning activation, DLC film thick 1-3μm hardness HV2000+, hydrophobic angle 110° achieving self-cleaning water bead roll-off. In application, coated barrels suit professional dry environments and high-speed styles, front thin film low-resistance accelerating release, mid composite texture transition, rear thick film fatigue-resistant. Internal protection cavities coating zone density balanced reinforcing lifespan. Compared to sandblasting, coating slippery enhancing fluency; compared to smooth, protective layer more scratch-resistant. Environmental vapor waste catalytic combustion, film stripping substrate recycled. Personalization friction preference custom film thickness, ensuring grip like slide rail. This coated reinforced defines protection longevity ceiling, advancing durable surface revolution.
