Cast steel wear parts as a ceramic composite
Cast steel wear parts as a ceramic composite
(OP)
I am interested in learning more about mmc as applicable to cast wear parts used in mining industries. Much of this work is patented and not readily available. I shall be thankful,if some of the concerns that I have can be addressed
Preforming of ceramic inserts to be placed in the mold cavity.
Improving wetability between liquid steel and inserts( I assume they are honeycomb type cassettes,placed)
Anchoring of the inserts appropriately so they do not flow off or get displaced while molten metal is poured.
How to determine the size of opening for the liquid steel to flow and cover the complete mass.
Any restriction on thickness of the insert or ratio of ceramic section thickness to the section thickness of the part.
These are very direct questions related to manufacture of wear parts. However, if I can get some information or literature references, I shall be very thankful.

RE: Cast steel wear parts as a ceramic composite
A cursory search on three different search engines didn't enlightened me about casting steel inserted ceramic inserts. I also took at the armor approach and it seems as all the effective is leaving rolled and cast armor plate and going with composites, like ceramic foam infiltrated with metal or another ceramic, or Al. foam infiltrated with ceramics.
I wonder if the Ferro-Tic materials would bond with cast steel Evidently you can bond metal infiltrated ceramic foam to steel at high temperatures.

The benefits to the end user is quite substantial,but there is a mindset to be altered, I am busy doing that.

RE: Cast steel wear parts as a ceramic composite
I went back in my notes from many years ago when the company I worked for made a gray iron body where they cast in some white iron bar for wear resistance. I haven't found anything yet but will keep looking since I worked on the project I should have my notes or a synopsis of the process. All I can remember is that they used a very dry sand. This sand was used with a sand slinger and still hand rammed after every hundred or so pounds of sand were added.

Here is another link to the origin of this pdf. It's a little hard to navigate but they appear to have a lot good information.
I'll try to get a better link to this site, Archives of Foundry Engineering

Article J. They are several others on this link. It seems that the proper term for ceramics in steel is calling it a composite.

On problem I originally had was that I looked at sites found using ceramic composites instead of metal composites.
