In the Specification of our International Patent Application PCT/GB 91/00950 there is described and claimed a method of securing against lateral motion two bodies held in face to face asperity contact, thereby to make a join between the two bodies, in which methods there is inserted into the interface between the two bodies a material that on minimal initial lateral relative motion of the two surfaces promotes rapid but controllable "galling" between the two surfaces, this galling binding the surfaces against further such motion. However, this method requires the two surfaces to fit well one to the other, and without such a good fit the resultant join may not be entirely satisfactory. The present invention's proposed solution to this gap problem is to use a metal-particle-containing composition comprising the gall enhancing agent loaded with a myriad of small metal particles, which composition can be packed into the gap, and will flow to accommodate a wide range of gap sizes and also to accommodate out-of-round distortion. The composition can take various physical forms, typically those of a free-flowing powder, a viscous liquid, or a stiff paste (and the powders have an additional use in the preparation of preforms for the manufacture of sintered parts).
