Leakproof, adhesive, non-lamellar and pore-free antifriction coatings can be produced from essentially oxidation-sensitive dispersion alloys, with at least two metallic alloy components forming a miscibility gap in the solid state, by means of vacuum plasma-spraying with a practically homogeneous material distribution. Precipitation crystallites of alloy components are significantly below 5 m

Bearing metal layer applied by vacuum plasma spraying to a support member directly or over an interlayer, comprising a dispersion alloy having at least two metallic components in a mixture leading to miscibility gaps, selected from the group consisting of aluminum-lead, aluminum-tin, and copper-lead

Bearing metal layer applied by vacuum plasma spraying to a support member directly or over an interlayer, comprising a dispersion alloy having at least two metallic components in a mixture leading to miscibility gaps, selected from the group consisting of aluminum-lead, aluminum-tin, and copper-lead dispersion alloys, said components, in the region of the miscibility gaps, forming a homogeneous alloy layer substantially free from pores, lamellae and stalk crystals, having uniformly dispersed fine particles comprising precipitation crystallites of one of said metallic components of a size substantially less than 5 microns and having a porosity of about 0% to 1%.
