Improvements in or relating to laminated metal structures for resisting wear at elevated temperatures. |
摘要 |
<p>A laminated metal structure and a method of hard-surfacing stainless steel base metals are herein provided for resisting wear of steam turbine components at elevated temperatures. The laminated metal structure employs a buttering layer, sandwiched between the stainless steel base metal and a hard-surfacing layer. The buttering layer consists essentially of nickel or a nickel-based alloy and is selected to have a coefficient of thermal expansion which is between that of the base metal and that of the hard-surfacing material. This improved structure produces a relatively crack-free deposit that can provide greater service life for turbine components with less downtime due to repairs.</p> |
