Thanks Greg,
You are confirming my perception supported by some real-life experience. My objective here is to make the case of the "open innovation" really open. I think that sharing information on the subject may make a good public service.

Gentlemen,
I appreciate your input but the business is more serious that it may appear to some of us. There seems to be, out there, a number of joints very likely supported by state or federal founds with the objective to envigorate and help to rebuilt innovative spirit of the American business...
Dear Fellow Engineers:
Any thoughts or past experience cases coming from your interaction with so called "Open Innovation" sites, like NineSigma, for instance?
The overall legal setup of such sites looks kind of hazy. Apparently they are fishing for ideas, yet there seems to be no transparency...
I do not necessarily agree with you but the outcome of the discussion might be prooving you right. I such case the reason for existence of such forums could be quite pointless.

Yes, HIPing seems to be one way to push it incrementaly to the higher level, for sure. It does not change the overall ball game, just pushes the microstructure closer to perfection. I appreciate the hint, however I am trying to bit bushes around with the hope to come-up with a better mousetrap...
I appreciate the link, however I am not in buy-sell type of business. I make what I sell. Obviously, one has to buy powders from places like Tosoh, etc. I am trying to figure-out a fundamental process to make custom blades. We can not delegate everything to China. In addition, such approach...
Yes Bruce, this is a kind of thinking I tried to pursue. Here, I rather thought of enriching the surface layer with yttria up to the level of full stabilization. The culprit here seems to be a depletion of yttria from tetragonal zirconia leading to monoclinic transformation. I would envision...
Thanks for the link, PratsA. This gets, more or less, to the heart of the problem: the inherent instability of the tetragonal phase ready to get transformed into the monoclinic. As the other respondents indicated one possibly marginal gain could be realized thru controlled processing of the...
It is a new project. The idea is to make lasting, reuseable cutting instrument. It is for medical application so sterilization is a must. Obviously other means of sterilizing could be considered but in real life it is the customer who makes the specs. Regarding the mode of failure: the ceramics...
Bruce,
I am trying to stay within the US-bounds. I have been exposed to bits and pieces of info regarding different types of zirconia ceramics. I made a number of commercial parts. One of the candidates is scandia-stabilized (or partially stabilized) material but it sets things back to the...
I am working on zirconia-3%yttria material cutting blades. The problem is that the blades have to be autoclave sterized. Under such conditions they may deteriorate. I am stuck with commercial 3%yttria material.
Is there a way to, say, surface modify the material in order to stabilize it without...
I would hope that the temperature in your system remains as low as feasible for your application. Say, you need min. 650 C, let's hope it does not exceed 1200 C. In such case you would have a lot of leeway utilising easy to fabricate and manage metallic heating element and a variety of heat...
