  • Patent number: 8344299
    Abstract: A cylinder heater useful in fabricating sleeves for high pressure pump liners comprises a support rotatably supporting a hollow circular cylinder having a metallic powder layer contacting a portion of its inner surface. A vibration sensor indicates vibration of the cylinder, and at least one temperature sensor indicates at least one temperature of the cylinder. At least one circumferential induction heating coil around the cylinder is positionable via the support along the longitudinal axis of cylinder rotation. Longitudinal position and power output of at least one heating coil, and cylinder rotational speed, are adjusted by a controller communicating with the support, the vibration sensor, at least one temperature sensor, and at least one heating coil. Controlled heating of the cylinder and the metallic powder layer results in a stratified abrasion-resistant fused metallic layer on the cylinder's inner surface. The fused layer may be honed to make a liner sleeve.
