Abstract (en)
[origin: EP0191008A1] A shell or tubular object, particularly having a complicated configuration, said object having an internal surface layer of a thermally sprayed, high temperature and corrosion resistant metal alloy and being intended to be incorporated in a machine or the like, especially in a combustion engine. When manufacturing the object, a relatively thin and essentially pore-free layer (2) is first sprayed onto a core body (1). Then, the core body (1) consisting of e.g. molding sand, is removed, whereupon a second layer (3) is sprayed onto the external surface of the first layer. The second layer (3) may have a substantially greater thickness without any risk for crack formation. The first, thinner layer (2) forms the internal surface layer of the object.
