How long can titanium alloy stay in the human body before going hot by rusting?

I plan on keeping mine in for the rest of my life with no rusting.  I would think that in a few million years if they find even my bones decayed away, that titanium will still be sittin' there shining nice and pretty.

yes!!!!\n\nrather be safe than sorry.  there might be one tiny part of rust that you cant even see on it.  and one shot last up to 7 years so just do it and get it over and done with!

Because it's a reactive form of metal and can easily form compounds. You wouldn't want a material in your body that's reactive otherwise you will be looking for more trouble.

A metal's corrosion (rusting) rate depends on its chemical properties. Some metals just take longer than others to corrode. Keep in mind that most metals have very high melting temperature, so in general high temperature doesn't contribute to the corrosion of a piece of metal just sitting in a damp space. For temperature to be of concern, it has to be around 700 degrees Celsius.\n\nI don't know much about your experiment, but you might not be using an appropriate metal sample. Most commonly found metals come with coatings or contain chemical inhibitors to prevent corrosion. Think about bikes sitting in outside in a humid (moisture-rich) environment. Manufacturers have to coat the metals to prevent this corrosion, or else no one would buy their product. This is the case with most metals. So if you just picked up something laying around the house and tried to corrode it, your experiment might not be successful. You should also be aware that only ferrous (iron) alloys rust, and the particular metal you tested might be something else.\n\nGo to google and type "rusting metal" (without the "s). The first four sites have lots of info.\n\n*It wouldn't rust in the freezer because there's no moisture in the freezer.

All materials that contain iron will rust, unless it contains very high amounts of carbon such as stainless steel that is. the simple answer to this question is all ferrous metals "rust" almost all others oxidise. oxidisation is caused when Oxygen and Water vapour attack the surface. the only natural metals that do not rust or oxidise are Gold and Silver. there are other exceptions too such as stainless steel but this is a man made alloy. A simple rule of thumb. if a magnet will stick to it. it will rust. another observation is when blood dries it goes a rust colour, this is because it contains high amounts of IRON

I've worked in health care for the past fifteen years.  It's always been my understanding that knee replacements/hip will usually last anywhere from eight to ten years depending on your weight and activity level.  If I'm wrong I hope someone else will clarify. This really isn't my area.  \n\nRod.

Here is an interesting fact.  The interior of our bones are lined with copper atoms.\nResearch it, its true.

I have had a total hip replacement for 13 years using titanium and a special plastic that fits between the ball and cup during winter I get pain between the hip and the knee this is said to be caused by the nerves near the hip .Metal ones like mine need to be taken care of so I dont dig holes ,jump or put any unnecessary force on the hip.Metal hips average life span is 10 years now there is a new type using some form of coral it is said to last 30 years and needs a smaller hole to be made in the leg .Some of my friends had partial hip replacements where either the femur or accetabulism is just replaced this is much more of a problem as getting the measuremenent right in a short time the doctor has is often difficult .I would not recommend that .For best results you need to strengthen your leg muscles a physiotheropist would show you if you cant afford one then follow my instructions ....Get a piece of masionite or thin plywood spread some talcum powder over it leave your sock on move the leg in and out lying flat on your back on the bed do that as much as possible then bending the knee bring your foot up toward your bottom again as long as you can then get a blanket or a few towels roll it up like a roll of paper place this under your thigh and raise and lower the lower leg again you can put a rice bag on the foot while doing this it helps the thigh muscle again as long as possible .There is a lot more I could tell you but that is the basics if you want to recover quickly.

No, I am pretty sure they would have used Titanium.  I have Titanium plate in my neck and will have it in my back soon.  I saw one of your other questions about metal detectors in the Airport and Titanium will not set off metal detectors or cause problems if you have to have an MRI.  Ask your Doctor what type of metal plate you have in your head but I know it won't rust.\n\nHope this helps!  :)

Solid in room temp, but melts in your hand (slightly above room temp)\n\nAlloys quickly with most metals.\n\nYou can read more at the following:

When iron rusts it oxidizes.  New atoms are being added to the iron, so of course the mass would increase.  In a closed system, lacking oxygen, iron wouldn't rust, so the law of conservation of mass and energy still holds.  When a match burns, it's losing mass as energy in the form of heat; again the law of conservation holds.

It's metal that you can set at a specific shape at higher than room temperature.\n\nWhen cooled it can be pulled out of shape but when heated again goes back to how it was set when heated for the first time.\n\nSee http://jchemed.chem.wisc.edu/JCESoft/CCA/CCA2/MAIN/MEMORYM/CD2R1.HTM

Yes, for a very short time, because it can quickly lower your body temp.  If you wait too long you will develop hypothermia and possibly die

Bathing in rusty water:  May not hurt you, but who wants to. It may discolor your hair, though.\n\nAnimals drinking:  They drink all kinds of impure water, but I wouldn't give them rusty water if I didn't have to.\n\nCooking: I would get some bottled water before I cooked with it. Even if you boil it first, the iron from the rust could be harmful over a period of time because it will not boil out.\n\nSome helpful advice: Instead of asking a new question (which costs you -5 points each) on an ongoing subject just edit your original question and people will come back to add to their previous answers or additional new answers may be posted.

An ounce of titanium is approximately 0.384 cubic inches.

Your question is a little hazy.  Are you looking for titanium?  Many different "elements", as in the periodic table, are in an engine.
