摘要： An injection valve for being in contact with an abrasive fluid has a cylinder having a cylinder length, an inner cylinder diameter and a cylinder wall, and a piston having an outer piston diameter and an outer piston face, the piston being movable in the cylinder. A first tubular liner is arranged between the cylinder wall and the piston so that the piston moves, at least partly, within the first tubular liner, the first tubular liner having a liner length, a first inner liner diameter and an inner liner face that has coating.

摘要： An exhaust valve spindle for an exhaust valve in an internal combustion engine has a shaft and a valve disc at the lower end of the shaft, which valve disc at its upper surface has a seat area. The seat area is of a seat material comprising at least from 34.0 to 44.0% Cr, an aggregate amount of Nb and Ta in the range from at least 2.8 to 6.1%, from 0.3 to 2.0% Ti, at the most 0.2% Al, at the most 0.04% B, at the most 0.8% Fe, at the most 0.04% C, at the most 0.4% Si, and a balance of Ni, where the amount of Ti+Nb+0.5×Ta is in the range from 3.4 to 6.6%, and where the amount of Nb+0.5×Ta is less than 3.0% if the amount of Ti is larger than 1.5%.
