  1. X EPNM – Bechichi 2010 TiTANIUM+ NiCKEL(1 + 1 mm) Ti Ni + EXPOSED TO THERMAL PROCESS LOADS Authors: Mariusz Prażmowski, Robert Bański, Zygmunt Szulc, Aleksander Gałka, Sebastian Kokot.

  2. TASKS According to ISO 9001 standard WORK IN WAY TO SATISFYTHECUSTOMER Basetasks: Additonallycan be: • Assure high quality of product • Recognize conditions of element exploitation • Check its influence for element’s durability • Offer acceptable price • Eventually correct technologicalparameters of manufacturing • Informthecustomeraboutresults of tests and examinations • Works and deliveries make in agreed time X EPNM – Bechichi 2010

  3. Application of Ti+Ni (1+1) mm Chlorineelectrolysis Membaraneelectrolyser Separate modul Bimetallic disc Ti + Ni Elektrolizer Bimetallic disc Ti + Ni Cathode(Ni) Detail of using X EPNM – Bechichi 2010 Anode (Ti)

  4. Identification of tasks Choose of parameters of cladding set • In high simply set – efect – bad bond Ni 201 Ti Gr.1 • Important changes in cladding set – getting improvement of bond Ni 201 Ti Gr.1 X EPNM – Bechichi 2010

  5. Identification of tasks Choose of optimal format of set • Preliminary set had sizes:1220 x 2000 mm. • Basis on costs analysis / problems such as: • Assembly in conditions of open area • Flatness of elements – Ti and Ni plates in delivery to cladding • Costs of straightening after cladding • In agreement with customer finally agreed sizes: 490 to 500 x 1250 mm X EPNM – Bechichi 2010

  6. Identification of tasks Choose of thermal loading to testing • (A) Simulation of loading connected with heating of element in process of jointing of cathode part – Nickiel with anode part – Titanium; possible methods • Resistance welding or microplasma welding or laser welding or electron beam welding Adoptedthatproper to modelling of loading will be heattreatment 610C / 1 h • (B) Simmulation of cladding process and regeneration active layers on anode (titanium). Adoptedthatproper to modelling of loading will be cycledheattreatment: 12 cycles – as on graph • Sample was heating during 5 minutes to temperature 480C, holding through 10 minutes, and next cooling through 20 minutes to room temperature (20C), in which was holding during 10 minutes. For each samples cycle of loading was repeated 12 times. X EPNM – Bechichi 2010

  7. Initiation point Identification of tasks Choose of thermal loading to testing - continuation • (C) Made heat treatment basis on heating of samples in temperature 500C in time 13 h • (D) Additionally – made heat treatment basis on joints (A) + (C), {610/1h} + 500C / 13h} • Samples to heat treatment were taking from productive element as below • Heat treatments were done in LAC furnace, model LMH 04/12 X EPNM – Bechichi 2010

  8. Tests and examinations MICROSTRUCTURALEXAMINATIONS • Conditions at the begining – without HT – test piece no. 1; a) x 200, b) x 500 • After HT 610C / 1 h – test piece no. 2; a) x 200, b) x 500, c) x 750 X EPNM – Bechichi 2010

  9. Tests and examinations MICROSTRUCTURALEXAMINATIONS • After HT 500C / 13 h; test piece no. 3; a) x 200, b) x 500, c) x 750 • After HT 610C / 1 h + 500C / 13 h; test piece no. 3; a) x 200, b) x 500, X EPNM – Bechichi 2010

  10. Tests and examinations HARDNESSEXAMINATIONS HV0,1 • TABLE OF RESULTS • Test piece no. 1 • Test piece no. 2 X EPNM – Bechichi 2010

  11. Tests and examinations HARDNESSEXAMINATIONS HV0,1 • GRAPH Ti Gr.1 Nickel Gr. 201 X EPNM – Bechichi 2010

  12. Tests and examinations TECHNOLOGICAL TEST • Shear test • For production are making 4 tests for batch of 50 pcs. X EPNM – Bechichi 2010

  13. Tests and examinations TECHNOLOGICALTESTS • Examples of results X EPNM – Bechichi 2010

  14. xplomet xplomet xplomet CONCLUSIONS • Examinations had strictly applicable character. • Any of heat treatment refer to conditions of manufacturing and exploitation of Ti + Ni has no negative influence for durability of bond. • Good made bond Ti+Ni cannot be broken by thermal loading on level of manufacturing techniques. • In aim to avoid any questions to speaker of this presentation, he let himself to make a question, for patienced and for sure borred audience – WHO WROTE THESE WORDS ? For 'tis the sport to have the enginerHoist with his own petard, an't shall go hardBut I will delve one yard below their minesAnd blow them at the moon. • THANKYOU FOR ATTENTION X EPNM – Bechichi 2010
