Additionally, the sound levels asso- ciated with KM are below occupational hazard levels, so the system does not require a soundproof booth to protect the operator. Sound levels are low enough that an operator posi- tioned at the control cabinet can run the systemwithout using personal hearing protection for an indefinite amount of time while complyingwithOSHA noise standards (OSHA 1910.95) [9] . Built-in process documentation . KM equipment provides precise process control and complete operating records. Sys- tems log all process data during operation and generate ob- jective quality evidence reports at the end of every coating session. Reports are traceable records of system operation and performance. These records can be checked later to verify correct coating application and proper system performance, which helps maintain consistency between runs and validate and certify the services performed. OTHER KM APPLICATIONS Kinetic metallization can be used to apply a wide variety of coating compositions on many component types and ge- ometries including: • • Turbopumps. KMWC-Co (HF-10-10) coatings are lapped to a flatness of <840 nm. • • Upstream oil exploration equipment. KM HF-20-30 is a corrosion resistant variation of KM HF-10-10 that passes 1000 hours of ASTM B117 salt fog testing while still exhib- iting a microindentation hardness of 900 HV 300g . • • Aerospace components. KM Al-Trans* 10-20-50 is a proven environmentally friendly, iron vapor deposition (IVD) and AlClad repair, as well as a replacement for brush cadmi- um, which offers superior corrosion protection and can be used for additive manufacturing and dimensional res- toration. • • Automotive engine components. KM WC-Co (HF-10-10) is routinely applied to repair vintage racing crankshafts. *Kinetic Metallization is a trademark, and Al-Trans is a regis- tered trademark, of Inovati. ~iTSSe For more information: Ralph Tapphorn is vice president of technology, Inovati, 1501 Cook Place, Santa Barbara, CA 93117, 805.571.6200, info@inovati.com , www.inovati.com .
