A mixture of two powdered alloys of the M, Cr, Al type, M being Co and/or Ni, is disclosed, in one form, for use in providing an abradable surface of an article and is characterized by the substantial absence of B. The first alloy has substantially no Si and has a higher melting range than that of the second alloy. The second alloy has substantially no Y and consists essentially of, by weight, 8-12% Si, 1.5-4% Al, 10-30% Cr, with the balance M and incidiental impurities. The total mixture composition consists essentially of, by weight, 10-35% Cr, 4-10% Al, from a small but effective amount up to about 0.09% Y, 2-6% Si, with the balance M and incidental impurities.

A mixture of two powdered alloys each comprising a base of elements M, Cr and Al in which M is at least one element selected from the group consisting of Co and Ni, the mixture having a total mixture composition consisting essentially of, by weight, 10-35% Cr, 4-10% Al, from a small but effective am
A mixture of two powdered alloys each comprising a base of elements M, Cr and Al in which M is at least one element selected from the group consisting of Co and Ni, the mixture having a total mixture composition consisting essentially of, by weight, 10-35% Cr, 4-10% Al, from a small but effective amount up to about 0.09% Y, 2-6% Si, with the balance M and incidental impurities, and further characterized by the substantial absence of B; a first of the powdered alloys having a solidus and a liquidus, consisting of 50-70 wt % of the mixture and having a melting range higher than a second of the powdered alloys; the first alloy characterized by the substantial absence of Si and the presence of Y in an amount, up to 0.15 wt %, which will provide the Y content in the total mixture composition; the second of the powdered alloys having a solidus and a liquidus, consisting essentially of the balance of the mixture, being characterized by the substantial absence of Y, and consisting essentially of, by weight, 8-12% Si, 1.5-4% Al, 10-30% Cr, with the balance M and incidental impurities.
