摘要

The blade comprises a current stumbling element, where current is applied along the prospective detachment position transversely to the required number of the current stumbling elements. The current is stoked up for laminar turbulent cover. The stumbling element is produced after the rough machining interrupts the finishing in the desired position. The stumbling elements are coated with a carbide containing hard metal by syringes, flame spraying or electrolytically.
