These surfaces are clad welded stainless steel around 2mm thick. We could flatten anomalies by stoning etc. but to coat them i.e. PTFE/ Nickel would mean major disassembly work and sending typ. 50Te of fabs for coating. A radical solution would be to remove the SS clad (and some of the base...
Thanks Tmoose, the design has been bought in from a reputable third party, however I think it's dodgy. We're stuck with this as to change it would be major. I have to decide whether to just hone off hi-spots or blue first and scrape. I cannot convince myself to use a scraper, if it were white...
Can someone advise: we are using 2 machined stainless steel 316 surfaces to transmit loading of a subsea unit (not ideal I know!). These surfaces will rotate relative to each other at a high contact load, albeit at low speed. In assembling the unit the surfaces have become damaged (scored)...
