{"product_id":"eaplsec","title":"Lab-Scale Electrochemical Cell (25 L, Pb Cathode) for Anodization and Polishing, EAPLSEC","description":"\u003cp\u003eA lab-scale electrochemical cell for anodization and electropolishing (EP) is designed to perform high-voltage dielectric oxide growth or controlled anodic dissolution on valve metals (Al, Ti, Zr, Nb, Ta) and alloys (stainless steel, Nitinol, Co-Cr).Both processes treat the workpiece as the anode, but they operate under divergent electrochemical regimes: electropolishing drives mass-transport-limited leveling and micro-smoothing, whereas anodization drives field-assisted oxide growth and self-assembled nanopore\/nanotube formation.\u003c\/p\u003e\n\u003cp\u003eRegarding the \u003cstrong\u003eanodization window\u003c\/strong\u003e: Operates either in the barrier-type regime (neutral electrolytes like ammonium borate, forming thin non-porous dielectric films) or the porous\/nanotubular regime (acidic electrolytes like oxalic, sulfuric, or fluoride-containing organic mixtures). High-field ionic conduction grows the oxide (A}^{3+} + O^{2-} to Al2O3), while field-assisted chemical dissolution etches the pore bottoms.\u003c\/p\u003e\n\u003cp\u003eRegarding the \u003cstrong\u003eelectropolishing (EP) window\u003c\/strong\u003e: Must be maintained on the mass-transport-limited plateau (j_lim). A viscous, high-resistance boundary layer (salt film \/ acceptor-depleted layer) forms over the surface. Protrusions and micro-asperities experience a steeper concentration gradient and dissolve faster than recessed valleys, yielding a mirror finish.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; height: 407.575px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 30.3384%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3406%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e EAPLSEC (E-AP-LSEC)\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 54.2px;\"\u003e\n\u003ctd style=\"width: 30.3384%; height: 54.2px;\"\u003e\u003cem\u003eDC Power Supply\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.3406%; height: 54.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan\u003eDC power source with output of 15 V\/30 A for operation.
