Titanium has unique material properties that affect maintenance:
| Property | Titanium (Grade 5) | Steel (Tool Steel) | Maintenance Implication |
|---|---|---|---|
| Corrosion resistance | Excellent (passive oxide layer) | Poor (rusts without coating) | Titanium can be autoclaved; steel cannot |
| Galling tendency | High (Ti‑on‑Ti seizes) | Low | Never use titanium tools against titanium fasteners without lubricant |
| Surface hardness | 36–42 HRC | 55–62 HRC | Titanium tips wear faster – inspect regularly |
| Magnetic susceptibility | < 5 × 10⁻⁶ | > 10² | Titanium never needs demagnetization |
Jovvi quality guarantee: Proper maintenance extends tool life to 10+ years under normal MRI service conditions.
Exposure: Occasional contact with patient fluids (saline, blood), contrast media (gadolinium), cleaning agents.
Risk: Gadolinium residue (paramagnetic) can contaminate tools, causing artifacts.
Maintenance requirement: Clean after every patient contact. Test for paramagnetic contamination monthly.
Jovvi recommendation: Dedicated Zone IV tool kit that never leaves the scanner room – reduces cross‑contamination.
Exposure: Liquid helium temperatures (-269°C) during cryogen work; helium vent gas (inert, no corrosion).
Risk: Thermal shock when moving tools from room temperature to cryostat port.
Maintenance requirement: Warm tools to room temperature before cleaning. Avoid rapid temperature changes (>10°C per minute).
Jovvi note: Grade 23 titanium retains toughness at cryogenic temperatures – no embrittlement risk.
Exposure: Humidity, dust, occasional contact with ferromagnetic particles from other tools.
Risk: Cross‑contamination from nearby steel tools (transfer of ferromagnetic dust).
Maintenance requirement: Store in closed Jovvi ABS case. Never store on magnetic parts tray.
Jovvi solution: Each kit includes a red‑labeled “MRI SAFE – NON‑MAGNETIC” case with foam inserts that hold tools securely.
| Tool Type | Inspection Frequency | Cleaning Method | Replacement Indicator |
|---|---|---|---|
| Hex keys (Grade 5 Ti) | Monthly | IPA wipe; ultrasonic if dirty | Worn hex corners (rounded) |
| Screwdrivers (Grade 5 blade) | Weekly (if used daily) | IPA wipe; inspect tip | Tip chipped or twisted |
| Sockets (Grade 5 Ti) | Monthly | Soap + water; dry immediately | Internal hex wallowing (loose fit) |
| Ratchet (Ti + Be‑Cu) | Quarterly | Disassemble, clean gears, re‑grease (Jovvi grease) | Slipping under torque |
| Torque wrench (Grade 23 + Be‑Cu) | Annually (calibration) | Wipe only – no solvent on spring | Calibration out of spec |
| Pliers (Ti jaws + bronze pivot) | Monthly | Lubricate pivot with silicone spray | Jaw misalignment or excessive play |
| Hammer (Ti head) | Quarterly | Inspect face inserts; clean head | Cracks in head (rare) |
| Tweezers (Grade 2 Ti) | As needed | Autoclave (121°C, 20 min) | Bent tips or loss of spring tension |
Jovvi titanium tools are autoclavable – a critical advantage over brass or aluminum tools that cannot withstand steam sterilization.
| Parameter | Setting |
|---|---|
| Temperature | 121°C (250°F) or 134°C (273°F) |
| Cycle time | 20 minutes (121°C) or 5 minutes (134°C) |
| Drying time | 15 minutes |
| Maximum cycles | Unlimited (no degradation) |
Caution: Do not autoclave tools with moving parts (ratchets, torque wrenches, pliers) – heat can damage lubricants and springs. Use low‑temperature sterilization (hydrogen peroxide plasma) for these tools.
After each use: Wipe with 70% isopropyl alcohol wipe. Remove all visible residue.
Weekly: Wash with mild soap and warm water using a soft brush. Rinse with deionized water. Dry completely with lint‑free cloth.
Monthly: Inspect for galling (titanium‑on‑titanium cold welding). If present, apply Jovvi anti‑galling paste (boron nitride based) to mating surfaces.
Quarterly: Ultrasonic cleaning (5 minutes in deionized water with mild detergent) – removes embedded particles from textured surfaces.
| Prohibited Substance | Reason |
|---|---|
| Chlorinated solvents ( methylene chloride) | Can attack some handle materials (plastics, grips) |
| Abrasive powders (pumice, sand) | Scrubs off passive oxide layer, promotes galling |
| Acidic cleaners (phosphoric, hydrochloric) | Etches titanium surface, reduces fatigue life |
| Steel wool or wire brushes | Leaves ferromagnetic particles embedded |
Galling is a form of adhesive wear where titanium cold‑welds to itself under pressure. This is the most common failure mode for titanium fasteners and tools.
Hex key feels “sticky” when removing from screw
Screw head hex recess becomes rounded or torn
Metallic debris (titanium flakes) visible on tool
| Application | Prevention Method |
|---|---|
| Titanium hex key into titanium screw | Use anti‑galling paste (Jovvi P/N JG‑100) – apply every 10 insertions |
| Titanium socket onto titanium nut | Nickel‑based anti‑seize (not containing molybdenum – that is ferromagnetic) |
| Titanium screwdriver into titanium fastener | Reduce insertion force – do not hammer seated |
| Any Ti‑on‑Ti threaded interface | Use brass or bronze insert as sacrificial interface |
