There are described construction parts for gaseous hydrogen containing media which construction parts are made of a nickel alloy containing 40 to 70% nickel, 15 to 30% chromium, 0 to 20% cobalt, 5 to 10% molybdenum, and 0 to 20% iron and which construction parts have optimum hydrogen permeation prevention properties. For this purpose, the alloys contain 0.5 to 0.8% manganese and the parts are provided with a 1 to 10 .mu.m thick oxide coating by treating at a temperature of 850.degree. to 1000.degree. C. in an oxidizing atmosphere.

A method for metallizing the surface of a carbon fiber reinforced plastic member by vapor-deposition of a metal layer in a high vacuum, with a glow treatment taking place before the vapor-deposition process. The surface of the plastic member to be metallized is removed until the carbon fibers lying closest to the surface are partially exposed. The plastic member is then degassed. A negative high voltage is applied across the degassed plastic member to bring about a glow treatment of the plastic member before the metal vapor-deposition. The glow treatment is continued into the initial phase of the metal vapor-deposition process.
